For example, the 'mini2' example profile builds a console-only system, +the 'xmaxi' profile boots to <em>xfce</em>. +</p> + +<p>One thing worth noting is that these supplied profiles automatically login +to the root account, which - potentially - allows all sorts of 'dangerous' actions, +like reformatting your disks or making a mess of your file-systems in other ways. +This is because one of the main <em>raisons d'être</em> for <em>larch</em> is its use +as an <em>Arch</em>-installation-and-rescue medium. For this, you need root access. +However, if you want to use the system in other ways, e.g. for text or image editing, +or for internet browsing or e-mail writing, it might be safer to do this as an +unprivileged user. Such a user is easily created with the 'adduser' command, or +with some other utility (e.g. the graphical 'luser.py' script in the <em>larch</em> +'<em>luser</em>' package). If you have a writeable boot medium, such changes can be +'remembered' by saving the session when you shut the system down (the possibility +will normally be offered automatically). +</p> + +<h3><a name="bootparm"></a>Boot parameters</h3> + +<p>As the <em>larch</em> build system is highly configurable, the available +boot parameters can also vary, but by default 'swap' and 'c2r' are provided. +'swap' indicates that an existing swap partition should be used (the default +is not to use it). 'c2r' means 'copy to RAM', i.e. the system data is copied +to main memory before the system is initialized. This allow the system to run +very fast and frees up the boot device (e.g. the boot CD can be ejected and the +drive used for another CD), but it does require a lot of memory (significantly +more than the size of the boot medium), and the boot process is rather slow +because so much data must be copied. Because of the high memory usage, I have +arranged it so that 'c2r' also implies 'swap'. With A USB-stick as boot medium, +the 'c2r' parameter should generally not really be needed, performance is normally +pretty good and it doesn't occupy the CD-drive (if an extra boot CD is needed, on +a machine that can't boot directly from USB, that can be removed after +booting even without 'c2r'). +</p> +<p>There are also boot options connected with the boot device. The 'nocd' boot +option, if present, prevents booting from CD. This might be useful if you use a +boot CD but want to boot a <em>larch</em> system on another device (normally +a CD will be detected before other devices). This only works if the kernel is +compatible of course. +</p> +<p>The 'root=' option allows explicit specification of the device containing the +<em>larch</em> system. It is also possible to choose the boot device on the basis +of UUID ('uuid=') or label ('label='). The default maximum waiting time (to +allow USB devices to be recognized) is 12 seconds (if a device is recognized +earlier the pause will automatically be shorter), which should be adequate, but +if you want to change this you can do it using the 'usbdelay=' option. +</p> + +<h3><a name="config"></a>Configuration</h3> + +<p>The supplied profiles are not intended to be complete, though I hope they +work reasonably well. They should be seen as examples, perhaps as starting points +for your own configurations. +If you are running a profile with X11, you may find that you +need to configure it before it will run, though nowadays much hardware will work +to at least some extent without any tweaking (even without an 'xorg.conf'). +Minimal starting-point 'xorg.conf' files are offered in the <em>xfce</em> examples. +</p> + +<p>The 'xmini' and 'xmaxi' profiles use a slightly more elaborate login approach on +the first terminal, with a simple menu as well as automatic login. There is also +a logout gui for <em>xfce</em>, which together with the login script can +trigger session saving directly, bypassing the console prompt. +</p> + +<p>If you are stuck with the console, there is still hope. It's not as pretty or +newbie friendly as an X11 desktop, but still quite capable. I always like to have +<em>mc</em> available, it's a real godsend for non-geeks (you should also install +<em>lynx</em> so that HTML files can be displayed on the console - at a +pinch you can also surf with it, but it is painful). +</p> + +<p>If your console keyboard map is +wrong, try running <i>km</i> (I stole this from the +standard <em>Arch</em> install CD and modified it a bit to work in <em>larch</em>). +It also modifies '/etc/rc.conf', so the change can be retained for subsequent +runs by performing a 'session-save'. +</p> + +<p>If you have a DHCP server on your network, you might well find that +the network interface is configured automatically (assuming your <em>rc.conf</em> +is configured appropriately). Otherwise you can use any method to set up +the network available in <em>Arch Linux</em> - see the appropriate +<em>Arch Linux</em> documentation (primarily the wiki, I guess) for details. +</p> + +<p>Of course the exact details of what you can do depends on what +software you installed, so I won't rabbit on endlessly about it here. +Nearly all configuration details should be just the same as in a normal, +hard-disk based installation. +</p> + +<h3><a name="install"></a>Installation to hard disk</h3> + +<p>The <em>larch</em> hard-disk installer <em>larchin</em> may be used to install +<em>Arch Linux</em> to hard disk (or similar). ***+ Or, at least it will be +possible to use it when I have updated (rewritten?) it for <em>larch</em>-7. -*** +<em>larchin</em> deals with partitioning and formatting of hard drives, placing +<em>Arch Linux</em> (primarily a copy of the live system on which it is running) +on the newly formatted partitions, and installation of the GRUB bootloader. +</p> + +<p>As mentioned above the main approach to <em>Arch</em> installation covered by +<em>larchin</em> is to copy the contents of the live system to a hard drive. Those +(few) bits peculiar to the needs of a live system are removed and the result is a +completely normal <em>Arch Linux</em> installation. I should perhaps mention +the file 'delarch' in the '/.livesys' directory (copied there from the 'larch/copy' +directory on the boot medium). This script (if it exists) is run at the end +of the installation +and allows custom installation actions to be performed (the +main reason for its existence is to allow features of the <em>live</em> system +to be removed, because they would be out of place in a normal installation). +</p> + +<h3><a name="install-live"></a>'Live' installation to hard disk</h3> +<p>This is sometimes called a 'frugal' install and means that the system +as it is (compressed, running in a <em>union</em> file system) on the +USB-stick or CD is installed as a <em>live</em> system to a hard-drive +partition. This might be useful if you want to run from a flash device, +for example, as it minimizes write operations to the device (normal access +is read only). +</p> +<p>The <strong>larch2hdd</strong> script (in the <em>larch-live</em> package) +performs such an installation. The partition for the installation should exist +before calling this script, which will format it as <em>ext2</em>. The script +will also install GRUB, either to the same partition or else to the MBR. +</p> + +<h3><a name="change-medium"></a>Copying the <em>live</em> system to other +media</h3> +<p>The bootloader configuration files for both isolinux(/syslinux) and grub +are copied to the medium when it is being built, regardless of which +bootloader has actually been selected. This will, however, only happen +if the support packages for the corresponding bootloader is installed in +the <em>live</em> system. This behaviour allows the <em>larch</em> scripts +to copy an already built system from one medium to another, retaining the +boot commands, and even switching the bootloader. See the +<a href="medium.html">documentation</a> for +the 'larch-live_iso' and 'larch-live_part' scripts. +</p> + +</div> + + + <div class="topref"><a href="#top">Top</a></div> + </div> + <!-- begin: #footer --> + <div id="footer"> + <div id="footer-content" role="contentinfo">© 2010 Michael Towers<br /> + Page layout assisted by <a href="http://www.yaml.de/">YAML</a> and + <a href="http://www.kuwata-lab.com/tenjin/">pyTenjin</a> + </div> + </div> + <!-- end: #footer --> + </div> + <!-- end: #col1 --> + <div id="bottom"><div id="bl"><div id="bm"></div></div></div> + </div> +</div> +<!-- full skiplink functionality in webkit browsers --> +<script src="css/yaml/core/js/webkit-focusfix.js" type="text/javascript"></script> +</body> +</html> |
