=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, Pulsar and U-Boot) and copy it with all
-other files needed for booting to a remote boot server.
+bootloaders are GRUB, GRUB2, ISOLINUX, Pulsar and U-Boot) and copy it
+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.
- ./script --server=192.168.1.1:/tftp --iprelay=192.168.1.2
-
-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
-host 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 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 have GRUB 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.

-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.

Novaboot performs its work in several phases. Each phase can be

=head2 Configuration reading phase
-After starting, novaboot reads configuration files. By default, it
-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 configuration files are read in
-order from the root directory downwards with latter files overriding
-settings from the former ones.
+After starting, novaboot reads configuration files. Their content is
+described in section L</"CONFIGURATION FILES">. By default,
+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 of English letters, numbers, dashes '-' and underscores '_'
+(note that dot '.' is not included) are read in alphabetical order.
+
+Then, the user configuration file is read from
+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, 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
-read from the standard input or when novaboot is invoked explicitly
-and options precede the script name, as in the example L</"4."> above.
-In this case the current working directory is used as a starting point
-for configuration file search.

+
+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.
