-<h2 id="pagetitle" level="1">Profiles</h2>
-
-<p>This feature of the <em>larch</em> build system allows bundling
-all the configuration information for a particular <em>live</em> system
-'design' into a single directory, a <em>larch profile</em>, and the
-name of the profile is the directory's name. This directory includes
-the list of packages to be installed, locale information and the
-particular tweaks and additions needed
-to customize the system, in particular a subdirectory containing the
-'overlay' files - those files which have been changed from their initial
-fresh state after installation and those which have simply been added.
-</p>
-
-<p>Note that of all the profile files and directories mentioned here
-only 'addedpacks' is not optional.
-</p>
-
-<h3><a name="overlay"></a>The overlay directory</h3>
-
-<p>One of the simplest features of the profile is perhaps the
-'<em>rootoverlay</em>' subdirectory:
-everything in this directory is copied directly to the
-<em>live</em> system's overlay, so that the a file 'a/b/c' within this
-directory will appear at '/a/b/c' in the <em>live</em> system, regardless
-of whether this file previously existed. Note however that all ownerships
-are changed to 'root:root'. The bulk of the customizations for the
-<em>live</em> system would normally be placed in this directory.
-</p>
-
-<p>It would be possible to make the desired alterations directly to the
-base system, and there are situations in which one would pretty well
-have to do it this way (for example if a modified or added file was to
-have some ownership other than 'root:root'). But another advantage (apart
-from the encapsulation of the customizations in the profile directory) of
-keeping the modifications in a separate directory is that the base
-installation can be kept 'clean' and thus it is easily reusable.
-</p>
-
-<p>If you would like to have a look at a profile, look in the 'profiles'
-directory in the 'larch-profiles' package (if you have downloaded
-<em>larch</em> by means of the 'larch-setup' script that will be
-'larch0/profiles'). Each of its subdirectories is a profile.
-If you want to make your own profile, it is probably easiest to start with
-one of the examples. Copy one of these directories to your working directory
-and rename it (to avoid confusion).
-</p>
-
-<h3><a name="cd-root"></a>The <strong>cd-root</strong> directory</h3>
-
-<p>This directory contains files that will be (more or less) directly copied
-to the <em>larch</em> medium, partly dependent on the available bootloaders.
-</p>
-
-<p>Bootloader independent files are provided in the 'larch' package at
-'cd-root/boot0'. Individual files can be added or substituted by
-supplying them in the <em>profile</em> at <strong>cd-root/boot</strong>.
-It is also possible to completely replace the basic boot directory by
-having <strong>cd-root/boot0</strong> in
-the profile - then the default version will not be used. These files are
-copied to the 'boot' directory of the bootable medium.
-</p>
-
-<p>There are also directories for bootloader dependent files. These are only
-copied over if the <em>live</em> system has support for the corresponding
-bootloader (i.e. if the corresponding packages - 'grub' and 'syslinux' - are
-installed). These end up as subdirectories of the medium's 'boot' directory,
-'boot/grub', 'boot/syslinux' or 'boot/isolinux', and work in a similar way to
-the 'boot(0)' directories. <em>larch</em> provides default versions of these
-directories in 'cd-root/grub0' and 'cd-root/isolinux0'. To extend these, or
-replace individual files, place your changes in the directories
-<strong>cd-root/grub</strong> and <strong>cd-root/isolinux</strong> in the
-<em>profile</em> directory, if
-you want to completely replace these directories, supply your versions in
-<strong>cd-root/grub0</strong> and <strong>cd-root/isolinux0</strong> in the
-profile directory.
-</p>
-
-<p>The contents of the directory <strong>cd-root/larch/copy</strong> will
-appear in '/larch/copy' on the medium. During booting the <em>larch live</em>
-system will copy the contents of this directory to the <em>tmpfs</em> base
-directory ('/.livesys'). This feature is not
-used by the <em>larch</em> system itself, but it can be used in various
-ways by the <em>live</em> system - the example profiles use it to some
-extent, for controlling autologin and for data required for installation
-as a normal <em>Arch</em> system (information on features specific to a
-<em>live</em> system which should be stripped out if a normal installation
-is performed).
-</p>
-
-<p>The contents of the directory <strong>cd-root/larch/extra</strong> will
-appear in 'larch/extra' on the medium but are otherwise unconnected with any
-<em>larch</em> functionality. <em>Live</em> system designers can use this
-in any way they like.
-</p>
-
-<h3><a name="other-files"></a>Other important files within a profile</h3>
-
-<ul>
- <li><strong>addedpacks</strong> - This is the only compulsory file in
- the profile (it must even be present if you are not using the
- installation stage, but it can be empty in that case). It contains
- a list of packages and package groups to be installed to the 'base'
- system. Here you can enter all the applications
- you would like in your <em>live</em> CD/USB system (and subsequently
- installed to a hard disk partition, if that was your intention).
- Thanks to <em>pacman</em> you don't need to sort out dependencies,
- these should all be included automatically. See
- <a href="archin.html#package_selection">here</a> for details.
- </li>
- <li><strong>vetopacks</strong> - Allows 'vetoing' of packages included
- indirectly in the installation list from 'addedpacks'. See
- <a href="archin.html#package_selection">here</a> for details.
- </li>
- <li><strong>pacman.conf.repos</strong> - Set the repository part of
- 'pacman.conf' for the <em>live</em> system, and possibly also for
- installation of the base system (See
- <a href="archin.html#pacman_conf">here</a> for further details).
- The default version will be adequate for many situations, but you
- will need to supply this file if you use the 'testing' repository,
- for example.
- </li>
- <li><strong>pacman.conf.options</strong> - Set the options part of
- 'pacman.conf' for the <em>live</em> system and for
- installation of the base system (See
- <a href="archin.html#pacman_conf">here</a> for further details).
- This will generally not be needed as the default version will be
- adequate for most purposes.
- </li>
- <li><strong>bootlines</strong> - This file contains bootloader independent
- boot lines, so that the same file can be used for grub and isolinux/syslinux.
- The gui provides a button to edit this file.
- To get an idea of what should be in here look at the default version (in
- the 'larch' package, 'data' directory), or just click on the edit button.
- </li>
-
- <li><strong>rootoverlay/etc/rc.conf</strong> - As a major point of
- configuration in an <em>Arch</em> system this is important enough
- to get a button in the <em>larch</em> gui to edit it.
- </li>
-
- <li><strong>rootoverlay/etc/locale.gen</strong> - For convenience, the
- <em>larch</em> gui provides a button to edit this file, which determines
- which glibc locales are supported in the <em>live</em> system. The
- corresponding files are generated (to the overlay) by the 'larchify'
- script, which has an option (for experts only) to reuse the locale
- files from a previous run (in order to reduce generation time in
- cases where the locales are unchanged).
- </li>
-
- <li><strong>rootoverlay/etc/mkinitcpio.conf.larch0</strong> - Again for
- convenience, the <em>larch</em> gui provides a button to edit this file,
- which allows you to tweak the initramfs. This is a special version of
- '/etc/mkinitcpio.conf' which is used to generate the initramfs for the
- <em>larch live</em> system. The default version is supplied as
- '/etc/mkinitcpio.conf.larch0' in the 'larch-live' package. Whatever else
- you change, don't change the larch hooks.
- </li>
-
- <li><strong>rootoverlay/etc/inittab.larch</strong> - If this file is
- present it will cause the original /etc/inittab to be saved with a
- '.larchsave' suffix, and this new version will be used for the
- <em>live</em> 'inittab'. This allows a special version of this file to
- be used just for the <em>live</em> system, an installer
- can replace it by the original during the installation process.
- </li>
-
- <li><strong>users</strong> - It is possible to add user accounts to the
- system during building. See below.
- </li>
-
- <li><strong>skel_*</strong> (directory) - Customized '/etc/skel' substitutes
- for use at build time only. See below.
- </li>
-
- <li><strong>vetodirs</strong> - Do not use this unless you really know what
- you are doing. Each directory listed in this file (one entry per line,
- comment lines start with '#') will be excluded from the live system. The
- directories are relative to the installation root.
- </li>
-
- <li><strong>build-tweak</strong> - Do not use this unless you really know
- what you are doing. It is a program (script) - so it must be executable -
- to customize the construction of the overlay (to a certain extent). It gets
- two arguments on the command line: the path to the installation being
- larchified, and the (full) path to the directory in which the overlay is
- being constructed. It is called just before 'mods.sqf' is squashed, but
- also before users are added.
- </li>
-
- <li><strong>nosave</strong> - The existence of this file will suppress the
- generation of the file 'larch/save' on a writable medium (unless overridden
- by an option to the medium generation script). It is also copied to
- 'larch/nosave' on the medium (also on non-writable media), so that this
- message is available later, e.g. when copying the medium.
- </li>
-
-</ul>
-
-<h3><a name="users"></a>Adding user accounts</h3>
-
-<p>
-The construction details should be provided in the 'users' file in the
-profile directory. It is an 'ini'-style configuration file, the sections
-being the user names. Here is an example:
-<pre>[DEFAULT]
-pw =
-expert =
-skel =
-maingroup =
-uid =
-xgroups = video,audio,optical,storage,scanner,power,camera
-
-[u1]
-uid = 999
-skel =
-
-[u2]
-pw = p1
-expert =
-skel =
-maingroup =
-uid =
-xgroups = video,audio,optical,storage
-</pre>
-The 'DEFAULT' section is not necessary, but is generated automatically
-by the gui user-table editor. Only entries which differ from the default
-values need be present.
-</p>
-<p>The default primary group is defined by settings in '/etc/login.defs'
-and '/etc/default/useradd' ('USERGROUPS_ENAB yes' in 'etc/login.defs'
-causes this to be a group with the same name as the user). You can
-override this by adding an 'expert' option, or by placing modified versions
-of these files in the profile's 'rootoverlay' directory.
-</p>
-<p>The additional groups should be comma-separated and without spaces.
-</p>
-<p>If no 'skel'-file is specified, the default ('/etc/skel') is used, including
-anything in the overlay. To use a custom 'skel'-file, place the directory
-in the profile, giving it a name starting with 'skel_', and place the rest of
-the name (the part after '_') in the configuration line.
-</p>
-<p>A password can be set for the new user by entering this (plain text -
-I'm guessing this is alright in this situation ...). An empty password
-field will allow passwordless logins (at least on the console).
-</p>
-<p>By default the UID number will be chosen automatically, but a specific
-number may be entered here. In <em>Arch Linux</em> the UIDs normally start
-at 1000.
-</p>
-<p>Users are added by means of 'useradd', so anything placed in the 'expert'
-field should be a valid option to that command. If a user-name already exists
-in the system to be larchified, it will be ignored (it does not count as
-an error).
