1175 novaboot - Boots a locally compiled operating system on a remote
1182 B<novaboot> [option]... [--] script...
1184 B<./script> [option]...
1188 This program makes booting of a locally compiled operating system (OS)
1189 (e.g. NOVA or Linux) on remote targets as simple as running a program
1190 locally. It automates things like copying OS images to a TFTP server,
1191 generation of bootloader configuration files, resetting of target
1192 hardware or redirection of target's serial line to stdin/out. Novaboot
1193 is highly configurable and it makes it easy to boot a single image on
1194 different targets or different images on a single target.
1196 Novaboot operation is controlled by command line options and by a so
1197 called novaboot script, which can be thought as a generalization of
1198 bootloader configuration files (see L</"NOVABOOT SCRIPT SYNTAX">).
1199 Typical way of using novaboot is to make the novaboot script
1200 executable and set its first line to I<#!/usr/bin/env novaboot>. Then,
1201 booting a particular OS configuration becomes the same as executing a
1202 local program - the novaboot script.
1204 Novaboot uses configuration files to, among other things, define
1205 command line options needed for different targets. Users typically use
1206 only the B<-t>/B<--target> command line option to select the target.
1207 Internally, this option expands to the pre-configured options.
1208 Configuration files are searched at multiple places, which allows to
1209 have per-system, per-user or per-project configurations. Configuration
1210 file syntax is described in section L</"CONFIGURATION FILE">.
1212 Simple examples of using C<novaboot>:
1218 Run an OS in Qemu. This is the default action when no other action is
1219 specified by command line switches. Thus running C<novaboot myos> (or
1220 C<./myos> as described above) will run Qemu and make it boot the
1221 configuration specified in the F<myos> script.
1225 Create a bootloader configuration file (currently supported
1226 bootloaders are GRUB, GRUB2, ISOLINUX, Pulsar and U-Boot) and copy it
1227 with all other files needed for booting to a remote boot server. Then
1228 use a TCP/IP-controlled relay/serial-to-TCP converter to reset the
1229 target and receive its serial output.
1231 ./myos --grub2 --server=192.168.1.1:/tftp --iprelay=192.168.1.2
1235 Run DHCP and TFTP server on developer's machine to boot the target
1240 This is useful when no network infrastructure is in place and
1241 the target is connected directly to developer's box.
1245 Create bootable ISO image.
1247 novaboot --iso -- script1 script2
1249 The created ISO image will have ISOLINUX bootloader installed on it
1250 and the boot menu will allow selecting between I<script1> and
1251 I<script2> configurations.
1255 =head1 PHASES AND OPTIONS
1257 Novaboot performs its work in several phases. Each phase can be
1258 influenced by several command line options, certain phases can be
1259 skipped. The list of phases (in the execution order) and the
1260 corresponding options follows.
1262 =head2 Configuration reading phase
1264 After starting, novaboot reads configuration files. Their content is
1265 described in section L</"CONFIGURATION FILE">. By default,
1266 configuration is read from multiple locations. First from the system
1267 configuration directory (F</etc/novaboot.d/>), second from the user
1268 configuration file (F<~/.config/novaboot>) and third from F<.novaboot>
1269 files along the path to the current directory. Alternatively, a single
1270 configuration file specified with the B<-c> switch or with the
1271 C<NOVABOOT_CONFIG> environment variable is read. The latter read files
1272 override settings from the former ones.
1274 The system configuration directory is determined by the content of
1275 NOVABOOT_CONFIG_DIR environment variable and defaults to
1276 F</etc/novaboot.d>. Files in this directory with names consisting
1277 solely of English letters, numbers, dashes '-' and underscores '_'
1278 (note that dot '.' is not included) are read in alphabetical order.
1280 Then, the user configuration file is read from
1281 F<$XDG_CONFIG_HOME/novaboot>. If C<$XDG_CONFIG_HOME> environemnt
1282 variable is not set F<~/.config/novaboot> is read instead.
1284 Finally, novaboot searches for files named F<.novaboot> starting from the
1285 directory of the novaboot script (or working directory, see bellow)
1286 and continuing upwards up to the root directory. The found
1287 configuration files are then read in the opposite order (i.e. from the
1288 root directory downwards). This allows to have, for example, a project
1289 specific configuration in F<~/project/.novaboot>.
1291 Note the difference between F<~/.config/novaboot> and F<~/.novaboot>.
1292 The former one is read always, whereas the latter only when novaboot
1293 script or working directory is under the C<$HOME> directory.
1295 In certain cases, the location of the novaboot script cannot be
1296 determined in this early phase. This happens either when the script is
1297 read from the standard input or when novaboot is invoked explicitly as
1298 in the example L</"4."> above. In this case the current working
1299 directory is used as a starting point for configuration file search
1300 instead of the novaboot script directory.
1304 =item -c, --config=I<filename>
1306 Use the specified configuration file instead of the default one(s).
1310 =head2 Command line processing phase
1316 Dump the current configuration to stdout end exit. Useful as an
1317 initial template for a configuration file.
1321 Print short (B<-h>) or long (B<--help>) help.
1323 =item -t, --target=I<target>
1325 This option serves as a user configurable shortcut for other novaboot
1326 options. The effect of this option is the same as specifying the
1327 options stored in the C<%targets> configuration variable under key
1328 I<target>. See also L</"CONFIGURATION FILE">.
1330 When this option is not given, novaboot tries to determine the target
1331 to use from either B<NOVABOOT_TARGET> environment variable or from
1332 B<$default_target> configuration file variable.
1336 =head2 Script preprocessing phase
1338 This phases allows to modify the parsed novaboot script before it is
1339 used in the later phases.
1343 =item -a, --append=I<parameters>
1345 Append a string to the first C<load> line in the novaboot script. This
1346 can be used to append parameters to the kernel's or root task's
1347 command line. This option can appear multiple times.
1351 Use F<bender> chainloader. Bender scans the PCI bus for PCI serial
1352 ports and stores the information about them in the BIOS data area for
1355 =item --chainloader=I<chainloader>
1357 Specifies a chainloader that is loaded before the kernel and other
1358 files specified in the novaboot script. E.g. 'bin/boot/bender
1363 Print the modules to boot and their parameters after this phase
1364 finishes. Then exit. This is useful for seeing the effect of other
1365 options in this section.
1367 =item -k, --kernel=F<file>
1369 Replace the first word on the first C<load> line in the novaboot
1370 script with F<file>.
1372 =item --scriptmod=I<perl expression>
1374 When novaboot script is read, I<perl expression> is executed for every
1375 line (in $_ variable). For example, C<novaboot
1376 --scriptmod=s/sigma0/omega6/g> replaces every occurrence of I<sigma0>
1377 in the script with I<omega6>.
1379 When this option is present, it overrides I<$script_modifier> variable
1380 from the configuration file, which has the same effect. If this option
1381 is given multiple times all expressions are evaluated in the command
1386 =head2 File generation phase
1388 In this phase, files needed for booting are generated in a so called
1389 I<build directory> (see L</--build-dir>). In most cases configuration
1390 for a bootloader is generated automatically by novaboot. It is also
1391 possible to generate other files using I<heredoc> or I<"<"> syntax in
1392 novaboot scripts. Finally, binaries can be generated in this phases by
1393 running C<scons> or C<make>.
1397 =item --build-dir=I<directory>
1399 Overrides the default build directory location.
1401 The default build directory location is determined as follows: If the
1402 configuration file defines the C<$builddir> variable, its value is
1403 used. Otherwise, it is the directory that contains the first processed
1406 See also L</BUILDDIR> variable.
1408 =item -g, --grub[=I<filename>]
1410 Generates grub bootloader menu file. If the I<filename> is not
1411 specified, F<menu.lst> is used. The I<filename> is relative to the
1412 build directory (see B<--build-dir>).
1414 =item --grub-preamble=I<prefix>
1416 Specifies the I<preable> that is at the beginning of the generated
1417 GRUB or GRUB2 config files. This is useful for specifying GRUB's
1420 =item --prefix=I<prefix>
1422 Specifies I<prefix> (e.g. F</srv/tftp>) that is put in front of every
1423 file name in generated bootloader configuration files (or in U-Boot
1426 If the I<prefix> contains string $NAME, it will be replaced with the
1427 name of the novaboot script (see also B<--name>).
1429 If the I<prefix> contains string $BUILDDIR, it will be replaced with
1430 the build directory (see also B<--build-dir>).
1434 Alias for B<--prefix>.
1436 =item --grub2[=I<filename>]
1438 Generate GRUB2 menu entry in I<filename>. If I<filename> is not
1439 specified F<grub.cfg> is used. The content of the menu entry can be
1440 customized with B<--grub-preamble>, B<--grub2-prolog> or
1441 B<--grub_prefix> options.
1443 In order to use the the generated menu entry on your development
1444 machine that uses GRUB2, append the following snippet to
1445 F</etc/grub.d/40_custom> file and regenerate your grub configuration,
1446 i.e. run update-grub on Debian/Ubuntu.
1448 if [ -f /path/to/nul/build/grub.cfg ]; then
1449 source /path/to/nul/build/grub.cfg
1452 =item --grub2-prolog=I<prolog>
1454 Specifies text that is put at the beginning of the GRUB2 menu entry.
1456 =item -m, --make[=make command]
1458 Runs C<make> to build files that are not generated by novaboot itself.
1460 =item --name=I<string>
1462 Use the name I<string> instead of the name of the novaboot script.
1463 This name is used for things like a title of grub menu or for the
1464 server directory where the boot files are copied to.
1468 Do not run external commands to generate files (i.e. "<" syntax and
1469 C<run> keyword). This switch does not influence generation of files
1470 specified with "<<WORD" syntax.
1472 =item -p, --pulsar[=mac]
1474 Generates pulsar bootloader configuration file named F<config-I<mac>>
1475 The I<mac> string is typically a MAC address and defaults to
1478 =item --scons[=scons command]
1480 Runs C<scons> to build files that are not generated by novaboot
1485 Strip I<rom://> prefix from command lines and generated config files.
1486 The I<rom://> prefix is used by NUL. For NRE, it has to be stripped.
1490 Exit novaboot after file generation phase.
1494 =head2 Target connection check
1496 If supported by the target, the connection to it is made and it is
1497 checked whether the target is not occupied by another novaboot
1502 =item --amt=I<"[user[:password]@]host[:port]>
1504 Use Intel AMT technology to control the target machine. WS management
1505 is used to powercycle it and Serial-Over-Lan (SOL) for input/output.
1506 The hostname or (IP address) is given by the I<host> parameter. If
1507 I<password> is not specified, environment variable AMT_PASSWORD is
1508 used. The I<port> specifies a TCP port for SOL. If not specified, the
1509 default is 16992. Default I<user> is admin.
1511 =item --iprelay=I<addr[:port]>
1513 Use TCP/IP relay and serial port to access the target's serial port
1514 and powercycle it. The IP address of the relay is given by I<addr>
1515 parameter. If I<port> is not specified, it default to 23.
1517 Note: This option is supposed to work with HWG-ER02a IP relays.
1519 =item -s, --serial[=device]
1521 Target's serial line is connected to host's serial line (device). The
1522 default value for device is F</dev/ttyUSB0>.
1524 The value of this option is exported in NB_NOVABOOT environment
1525 variable to all subprocesses run by C<novaboot>.
1527 =item --stty=I<settings>
1529 Specifies settings passed to C<stty> invoked on the serial line
1530 specified with B<--serial> option. If this option is not given,
1531 C<stty> is called with C<raw -crtscts -onlcr 115200> settings.
1533 =item --remote-cmd=I<cmd>
1535 Command that mediates connection to the target's serial line. For
1536 example C<ssh server 'cu -l /dev/ttyS0'>.
1538 =item --remote-expect=I<string>
1540 Wait for reception of I<string> after establishing the remote
1543 =item --remote-expect-silent=I<string>
1545 The same as B<--remote-expect> except that the remote output is not
1546 echoed to stdout while waiting for the I<string>. Everything after the
1547 matched string is printed to stdout, so you may want to include line
1548 end characters in the I<string> as well.
1552 =head2 File deployment phase
1554 In some setups, it is necessary to copy the files needed for booting
1555 to a particular location, e.g. to a TFTP boot server or to the
1560 =item -d, --dhcp-tftp
1562 Turns your workstation into a DHCP and TFTP server so that the OS can
1563 be booted via PXE BIOS (or similar mechanism) on the test machine
1564 directly connected by a plain Ethernet cable to your workstation.
1566 The DHCP and TFTP servers requires root privileges and C<novaboot>
1567 uses C<sudo> command to obtain those. You can put the following to
1568 I</etc/sudoers> to allow running the necessary commands without asking
1571 Cmnd_Alias NOVABOOT = /bin/ip a add 10.23.23.1/24 dev eth0, /bin/ip l set dev eth0 up, /usr/sbin/dhcpd -d -cf dhcpd.conf -lf dhcpd.leases -pf dhcpd.pid, /usr/sbin/in.tftpd --listen --secure -v -v -v --pidfile tftpd.pid *, /usr/bin/touch dhcpd.leases, /usr/bin/pkill --pidfile=dhcpd.pid, /usr/bin/pkill --pidfile=tftpd.pid
1572 your_login ALL=NOPASSWD: NOVABOOT
1576 Starts a TFTP server on your workstation. This is similar to
1577 B<--dhcp-tftp> except that DHCP server is not started.
1579 The TFTP server require root privileges and C<novaboot> uses C<sudo>
1580 command to obtain those. You can put the following to I</etc/sudoers>
1581 to allow running the necessary commands without asking for password.
1583 Cmnd_Alias NOVABOOT = /usr/sbin/in.tftpd --listen --secure -v -v -v --pidfile tftpd.pid *, /usr/bin/pkill --pidfile=tftpd.pid
1584 your_login ALL=NOPASSWD: NOVABOOT
1586 =item --tftp-port=I<port>
1588 Port to run the TFTP server on. Implies B<--tftp>.
1590 =item --iso[=filename]
1592 Generates the ISO image that boots NOVA system via GRUB. If no filename
1593 is given, the image is stored under I<NAME>.iso, where I<NAME> is the name
1594 of the novaboot script (see also B<--name>).
1596 =item --server[=[[user@]server:]path]
1598 Copy all files needed for booting to another location. The files will
1599 be copied (by B<rsync> tool) to the directory I<path>. If the I<path>
1600 contains string $NAME, it will be replaced with the name of the
1601 novaboot script (see also B<--name>).
1603 =item --rsync-flags=I<flags>
1605 Specifies which I<flags> are appended to F<rsync> command line when
1606 copying files as a result of I<--server> option.
1610 If B<--server> is used and its value ends with $NAME, then after
1611 copying the files, a new bootloader configuration file (e.g. menu.lst)
1612 is created at I<path-wo-name>, i.e. the path specified by B<--server>
1613 with $NAME part removed. The content of the file is created by
1614 concatenating all files of the same name from all subdirectories of
1615 I<path-wo-name> found on the "server".
1619 Use Intel AMT technology for IDE redirection. This allows the target
1620 machine to boot from novaboot created ISO image. Implies B<--iso>.
1622 The experimental C<amtider> utility needed by this option can be
1623 obtained from https://github.com/wentasah/amtterm.
1627 =head2 Target power-on and reset phase
1629 At this point, the target is reset (or switched on/off). There is
1630 several ways how this can be accomplished. Resetting a physical target
1631 can currently be accomplished by the following options: B<--amt>,
1632 B<--iprelay>, B<--reset-cmd>.
1638 Switch on/off the target machine and exit. The script (if any) is
1639 completely ignored. Currently it works only with B<--iprelay> or
1642 =item -Q, --qemu[=I<qemu-binary>]
1644 Boot the configuration in qemu. Optionally, the name of qemu binary
1645 can be specified as a parameter.
1647 =item --qemu-append=I<flags>
1649 Append I<flags> to the default qemu flags (QEMU_FLAGS variable or
1650 C<-cpu coreduo -smp 2>).
1652 =item -q, --qemu-flags=I<flags>
1654 Replace the default qemu flags (QEMU_FLAGS variable or C<-cpu coreduo
1655 -smp 2>) with I<flags> specified here.
1657 =item --reset-cmd=I<cmd>
1659 Command that resets the target.
1661 =item --no-reset, --reset
1663 Disable/enable resetting of the target.
1667 =head2 Interaction with the bootloader on the target
1671 =item --uboot[=I<prompt>]
1673 Interact with U-Boot bootloader to boot the thing described in the
1674 novaboot script. I<prompt> specifies the U-Boot's prompt (default is
1675 "=> ", other common prompts are "U-Boot> " or "U-Boot# ").
1676 Implementation of this option is currently tied to a particular board
1677 that we use. It may be subject to changes in the future!
1681 Disable U-Boot interaction previously enabled with B<--uboot>.
1685 Command(s) to send the U-Boot bootloader before loading the images and
1686 booting them. This option can be given multiple times. After sending
1687 commands from each option novaboot waits for U-Boot I<prompt>.
1689 If the command contains string I<$NB_MYIP> then this string is
1690 replaced by IPv4 address of eth0 interface. Similarly I<$NB_PREFIX> is
1691 replaced with prefix given by B<--prefix>.
1693 See also C<uboot> keyword in L</"NOVABOOT SCRIPT SYNTAX">).
1695 =item --uboot-addr I<name>=I<address>
1697 Load address of U-Boot's C<tftpboot> command for loading I<name>,
1698 where name is one of I<kernel>, I<ramdisk> or I<fdt> (flattened device
1701 The default addresses are ${I<name>_addr_r}, i.e. U-Boot environment
1702 variables used by convention for this purpose.
1704 =item --uboot-cmd=I<command>
1706 Specifies U-Boot command used to execute the OS. If the command
1707 contains strings C<$kernel_addr>, C<$ramdisk_addr>, C<$fdt_addr>,
1708 these are replaced with the addresses configured with B<--uboot-addr>.
1710 The default value is
1712 bootm $kernel_addr $ramdisk_addr $fdt_addr
1714 or the C<UBOOT_CMD> variable if defined in the novaboot script.
1718 =head2 Target interaction phase
1720 In this phase, target's serial output is redirected to stdout and if
1721 stdin is a TTY, it is redirected to the target's serial input allowing
1722 interactive work with the target.
1726 =item --exiton=I<string>
1728 When I<string> is sent by the target, novaboot exits. This option can
1729 be specified multiple times, in which case novaboot exits whenever
1730 either of the specified strings is sent.
1732 If I<string> is C<-re>, then the next B<--exiton>'s I<string> is
1733 treated as regular expression. For example:
1735 --exiton -re --exiton 'error:.*failed'
1737 =item --exiton-re=I<regex>
1739 The same as --exiton -re --exiton I<regex>.
1741 =item --exiton-timeout=I<seconds>
1743 By default B<--exiton> waits for the string match forever. When this
1744 option is specified, "exiton" timeouts after the specifies number of
1745 seconds and novaboot returns non-zero exit code.
1747 =item -i, --interactive
1749 Setup things for interactive use of target. Your terminal will be
1750 switched to raw mode. In raw mode, your system does not process input
1751 in any way (no echoing of entered characters, no interpretation
1752 special characters). This, among others, means that Ctrl-C is passed
1753 to the target and does no longer interrupt novaboot. Use "~~."
1754 sequence to exit novaboot.
1756 =item --no-interaction, --interaction
1758 Skip resp. force target interaction phase. When skipped, novaboot exits
1759 immediately when boot is initiated.
1761 =item --expect=I<string>
1763 When I<string> is received from the target, send the string specified
1764 with the subsequent B<--send*> option to the target.
1766 =item --expect-re=I<regex>
1768 When target's output matches regular expression I<regex>, send the
1769 string specified with the subsequent B<--send*> option to the target.
1771 =item --expect-raw=I<perl-code>
1773 Provides direct control over Perl's Expect module.
1775 =item --send=I<string>
1777 Send I<string> to the target after the previously specified
1778 B<--expect*> was matched in the target's output. The I<string> may
1779 contain escape sequences such as "\n".
1781 Note that I<string> is actually interpreted by Perl, so it can contain
1782 much more that escape sequences. This behavior may change in the
1785 Example: C<--expect='login: ' --send='root\n'>
1787 =item --sendcont=I<string>
1789 Similar to B<--send> but continue expecting more input.
1791 Example: C<--expect='Continue?' --sendcont='yes\n'>
1795 =head1 NOVABOOT SCRIPT SYNTAX
1797 The syntax tries to mimic POSIX shell syntax. The syntax is defined
1798 with the following rules.
1800 Lines starting with "#" and empty lines are ignored.
1802 Lines that end with "\" are concatenated with the following line after
1803 removal of the final "\" and leading whitespace of the following line.
1805 Lines of the form I<VARIABLE=...> (i.e. matching '^[A-Z_]+=' regular
1806 expression) assign values to internal variables. See L</VARIABLES>
1809 Lines starting with C<load> keyword represent modules to boot. The
1810 word after C<load> is a file name (relative to the build directory
1811 (see B<--build-dir>) of the module to load and the remaining words are
1812 passed to it as the command line parameters.
1814 When the C<load> line ends with "<<WORD" then the subsequent lines
1815 until the line containing solely WORD are copied literally to the file
1816 named on that line. This is similar to shell's heredoc feature.
1818 When the C<load> line ends with "< CMD" then command CMD is executed
1819 with F</bin/sh> and its standard output is stored in the file named on
1820 that line. The SRCDIR variable in CMD's environment is set to the
1821 absolute path of the directory containing the interpreted novaboot
1824 Lines starting with C<run> keyword contain shell commands that are run
1825 during file generation phase. This is the same as the "< CMD" syntax
1826 for C<load> keyboard except that the command's output is not
1827 redirected to a file. The ordering of commands is the same as they
1828 appear in the novaboot script.
1830 Lines starting with C<uboot> represent U-Boot commands that are sent
1831 to the target if B<--uboot> option is given. Having a U-Boot line in
1832 the novaboot script is the same as passing an equivalent
1833 B<--uboot-init> option to novaboot. The C<uboot> keyword can be
1834 suffixed with timeout specification. The syntax is C<uboot:Ns>, where
1835 C<N> is the whole number of seconds. If the U-Boot command prompt does
1836 not appear before the timeout, novaboot fails. The default timeout is
1841 #!/usr/bin/env novaboot
1842 load bzImage console=ttyS0,115200
1843 run make -C buildroot
1844 load rootfs.cpio < gen_cpio buildroot/images/rootfs.cpio "myapp->/etc/init.d/S99myapp"
1846 Example (NOVA User Land - NUL):
1848 #!/usr/bin/env novaboot
1849 WVDESC=Example program
1850 load bin/apps/sigma0.nul S0_DEFAULT script_start:1,1 \
1851 verbose hostkeyb:0,0x60,1,12,2
1852 load bin/apps/hello.nul
1853 load hello.nulconfig <<EOF
1854 sigma0::mem:16 name::/s0/log name::/s0/timer name::/s0/fs/rom ||
1855 rom://bin/apps/hello.nul
1858 This example will load three modules: F<sigma0.nul>, F<hello.nul> and
1859 F<hello.nulconfig>. sigma0 receives some command line parameters and
1860 F<hello.nulconfig> file is generated on the fly from the lines between
1861 C<<<EOF> and C<EOF>.
1865 The following variables are interpreted in the novaboot script:
1871 Novaboot chdir()s to this directory before file generation phase. The
1872 directory name specified here is relative to the build directory
1873 specified by other means (see L</--build-dir>).
1877 Assigning this variable has the same effect as specifying L</--exiton>
1880 =item HYPERVISOR_PARAMS
1882 Parameters passed to hypervisor. The default value is "serial", unless
1883 overridden in configuration file.
1887 The kernel to use instead of the hypervisor specified in the
1888 configuration file with the C<$hypervisor> variable. The value should
1889 contain the name of the kernel image as well as its command line
1890 parameters. If this variable is defined and non-empty, the variable
1891 HYPERVISOR_PARAMS is not used.
1895 If this variable is 1, the system is not booted. This is currently
1896 only implemented for U-Boot bootloader where it is useful for
1897 interacting with the bootloader without booting the system - e.g. for
1902 Use a specific qemu binary (can be overridden with B<-Q>) and flags
1903 when booting this script under qemu. If QEMU_FLAGS variable is also
1904 specified flags specified in QEMU variable are replaced by those in
1909 Use specific qemu flags (can be overridden with B<-q>).
1913 See L</--uboot-cmd>.
1917 Description of the WvTest-compliant program.
1919 =item WVTEST_TIMEOUT
1921 The timeout in seconds for WvTest harness. If no complete line appears
1922 in the test output within the time specified here, the test fails. It
1923 is necessary to specify this for long running tests that produce no
1924 intermediate output.
1928 =head1 CONFIGURATION FILE
1930 Novaboot can read its configuration from one or more files. By
1931 default, novaboot looks for files in F</etc/novaboot.d>, file
1932 F<~/.config/novaboot> and files named F<.novaboot> as described in
1933 L</Configuration reading phase>. Alternatively, configuration file
1934 location can be specified with the B<-c> switch or with the
1935 NOVABOOT_CONFIG environment variable. The configuration file has Perl
1936 syntax (i.e. it is better to put C<1;> as the last line) and should set
1937 values of certain Perl variables. The current configuration can be
1938 dumped with the B<--dump-config> switch. Some configuration variables
1939 can be overridden by environment variables (see below) or by command
1942 Supported configuration variables include:
1948 Build directory location relative to the location of the configuration
1951 =item $default_target
1953 Default target (see below) to use when no target is explicitly
1954 specified with the B<--target> command line option or
1955 B<NOVABOOT_TARGET> environment variable.
1959 Hash of target definitions to be used with the B<--target> option. The
1960 key is the identifier of the target, the value is the string with
1961 command line options. For instance, if the configuration file contains:
1963 $targets{'mybox'} = '--server=boot:/tftproot --serial=/dev/ttyUSB0 --grub',
1965 then the following two commands are equivalent:
1967 ./myos --server=boot:/tftproot --serial=/dev/ttyUSB0 --grub
1972 =head1 ENVIRONMENT VARIABLES
1974 Some options can be specified not only via config file or command line
1975 but also through environment variables. Environment variables override
1976 the values from configuration file and command line parameters
1977 override the environment variables.
1981 =item NOVABOOT_CONFIG
1983 Name of the novaboot configuration file to use instead of the default
1986 =item NOVABOOT_CONFIG_DIR
1988 Name of the novaboot configuration directory. When not specified
1989 F</etc/novaboot.d> is used.
1991 =item NOVABOOT_TARGET
1993 Name of the novaboot target to use. This overrides the value of
1994 B<$default_target> from the configuration file and can be overriden
1995 with the B<--target> command line option.
1997 =item NOVABOOT_BENDER
1999 Defining this variable has the same meaning as B<--bender> option.
