## Documentation
=head1 NAME
-novaboot - A tool for booting various operating systems on various hardware or in qemu
+novaboot - Boots a locally compiled operating system on a remote
+target or in qemu
=head1 SYNOPSIS
=head1 DESCRIPTION
-This program makes booting of an operating system (e.g. NOVA or Linux)
-as simple as running a local program. It facilitates booting on local
-or remote hosts or in emulators such as qemu. Novaboot operation is
-controlled by command line options and by a so called novaboot script,
-which can be thought as a generalization of bootloader configuration
-files (see L</"NOVABOOT SCRIPT SYNTAX">). Based on this input,
-novaboot setups everything for the target host to boot the desired
-configuration, i.e. it generates the bootloader configuration file in
-the proper format, deploy the binaries and other needed files to
-required locations, perhaps on a remote boot server and reset the
-target host. Finally, target host's serial output is redirected to
-standard output if that is possible.
-
+This program makes booting of a locally compiled operating system (OS)
+(e.g. NOVA or Linux) on remote targets as simple as running a program
+locally. It automates things like copying OS images to a TFTP server,
+generation of bootloader configuration files, resetting of target
+hardware or redirection of target's serial line to stdin/out. Novaboot
+is highly configurable and it makes it easy to boot a single image on
+different targets or different images on a single target.
+
+Novaboot operation is controlled by command line options and by a so
+called novaboot script, which can be thought as a generalization of
+bootloader configuration files (see L</"NOVABOOT SCRIPT SYNTAX">).
Typical way of using novaboot is to make the novaboot script
executable and set its first line to I<#!/usr/bin/env novaboot>. Then,
booting a particular OS configuration becomes the same as executing a
local program - the novaboot script.
-For example, with C<novaboot> you can:
+Novaboot uses configuration files to, among other things, define
+command line options needed for different targets. Users typically use
+only the B<-t>/B<--target> command line option to select the target.
+Internally, this option expands to the pre-configured options.
+Configuration files are searched at multiple places, which allows to
+have per-system, per-user or per-project configurations. Configuration
+file syntax is described in section L</"CONFIGURATION FILES">.
+
+Simple examples of using C<novaboot>:
=over 3
=item 1.
-Run an OS in Qemu. This is the default action when no other action is
-specified by command line switches. Thus running C<novaboot ./script>
-(or C<./script> as described above) will run Qemu and make it boot the
-configuration specified in the F<script>.
+Run an OS in Qemu. This is can be specified with the B<--qemu> option.
+Thus running C<novaboot --qemu myos> (or C<./myos --qemu> as described
+above) will run Qemu and make it boot the configuration specified in
+the F<myos> script.
=item 2.
Create a bootloader configuration file (currently supported
bootloaders are GRUB, GRUB2, ISOLINUX, Pulsar and U-Boot) and copy it
-with all other files needed for booting to a remote boot server.
-
- ./script --server=192.168.1.1:/tftp --iprelay=192.168.1.2
+with all other files needed for booting to a remote boot server. Then
+use a TCP/IP-controlled relay/serial-to-TCP converter to reset the
+target and receive its serial output.
-This command copies files to the TFTP server and uses
-TCP/IP-controlled relay to reset the target host and receive its
-serial output.
+ ./myos --grub2 --server=192.168.1.1:/tftp --iprelay=192.168.1.2
=item 3.
-Run DHCP and TFTP server on developer's machine to PXE-boot the target
-machine from it. E.g.
+Run DHCP and TFTP server on developer's machine to boot the target
+from it.
- ./script --dhcp-tftp
+ ./myos --dhcp-tftp
-When a PXE-bootable machine is connected via Ethernet to developer's
-machine, it will boot the configuration described in the I<script>.
+This is useful when no network infrastructure is in place and
+the target is connected directly to developer's box.
=item 4.
-Create bootable ISO images. E.g.
+Create bootable ISO image.
novaboot --iso -- script1 script2
-The created ISO image will use ISOLINUX bootloader installed on it and
-the boot menu will allow selecting between I<script1> and I<script2>
-configurations.
+The created ISO image will have ISOLINUX bootloader installed on it
+and the boot menu will allow selecting between I<script1> and
+I<script2> configurations.
=back
-Note that the options needed for a specific target can be stored in a
-L</"CONFIGURATION FILE">. Then it is sufficient to use only the B<-t>
-option to specify the name of the target.

+Each phase is described in the following sections together with the

=head2 Configuration reading phase
After starting, novaboot reads configuration files. Their content is
-described in section L</"CONFIGURATION FILE">. By default,
-configuration is read from two locations. First from the configuration
-directory and second from F<.novaboot> files along the path to the
-current directory. The later read files override settings from the
-former ones.

+configuration is read from multiple locations. First from the system
+configuration directory (F</etc/novaboot.d/>), second from the user
+configuration file (F<~/.config/novaboot>) and third from F<.novaboot>
+files along the path to the current directory. Alternatively, a single
+configuration file specified with the B<-c> switch or with the
+C<NOVABOOT_CONFIG> environment variable is read. The latter read files
+override settings from the former ones.
+
+The system configuration directory is determined by the content of
+NOVABOOT_CONFIG_DIR environment variable and defaults to
F</etc/novaboot.d>. Files in this directory with names consisting
-solely from English letters, numbers, dashes '-' and underscores '_'

+F<$XDG_CONFIG_HOME/novaboot>. If C<$XDG_CONFIG_HOME> environemnt
+variable is not set F<~/.config/novaboot> is read instead.
+
+Finally, novaboot searches for files named F<.novaboot> starting from the
directory of the novaboot script (or working directory, see bellow)
and continuing upwards up to the root directory. The found
configuration files are then read in the opposite order (i.e. from the
-root directory downwards). This allows to have, for example, user
-specific configuration in F<~/.novaboot> and project specific one in
-F<~/project/.novaboot>.
+root directory downwards). This allows to have, for example, a project
+specific configuration in F<~/project/.novaboot>.
+
+Note the difference between F<~/.config/novaboot> and F<~/.novaboot>.
+The former one is read always, whereas the latter only when novaboot
+script or working directory is under the C<$HOME> directory.
In certain cases, the location of the novaboot script cannot be
determined in this early phase. This happens either when the script is

+B<$default_target> configuration file variable.

+=item --uboot-cmd=I<command>

sequence to exit novaboot.
+=item --no-interaction, --interaction
+
+Skip resp. force target interaction phase. When skipped, novaboot exits
+immediately when boot is initiated.
+
=item --expect=I<string>
When I<string> is received from the target, send the string specified
redirected to a file. The ordering of commands is the same as they
appear in the novaboot script.
+Lines starting with C<uboot> represent U-Boot commands that are sent
+to the target if B<--uboot> option is given. Having a U-Boot line in
+the novaboot script is the same as passing an equivalent
+B<--uboot-init> option to novaboot. The C<uboot> keyword can be
+suffixed with timeout specification. The syntax is C<uboot:Ns>, where
+C<N> is the whole number of seconds. If the U-Boot command prompt does
+not appear before the timeout, novaboot fails. The default timeout is
+10 seconds.
