Well here is a little description of what DrakX needs to work in comparison to the RH newt install. ******************************************************************************** * CVS ************************************************************************** ******************************************************************************** Like all good free software, DrakX is in CVS :) You can access it at http://cvs.mandriva.com/cgi-bin/cvsweb.cgi/gi or via export CVS_RSH=ssh export CVSROOT=:ext:anoncvs@cvs.mandriva.com:/cooker cvs checkout gi (enter password 'cvs') This is only read-only access. If you want more, tell me (pixel@mandriva.com) Alas, all is not in CVS, a lot of things come from rpm packages which you must install. Please note that redoing *all* the stuff is not for the faint of heart. I myself sometimes wonder what the whole make does :-% Instead, changing some .pm files is quite easy (nice interpreted language) ******************************************************************************** * Making your custom install *************************************************** ******************************************************************************** If you have your own rpms you want to add, or make your own updated cdrom, you just have to issue: % gendistrib --noclean --distrib <DIRS> Where <DIRS> is the root of all the media that the install will see, this first one is the main one : (1) network or 1-cdrom installs DIRS == the root directory of the Distribution (2) multi-cdrom install DIRS == the root directories of all the media that the install will see ``gendistrib'' will scan the file media/media_info/hdlists in the main root directory (the first one in DIRS) to search for all media used. Typically you use media/main for RPM packages repository. For multi-cd, please use media/main or media/foo, etc. For one CD or a network/hd volume, please use media/main. Optionnally, you can modify ``media/media_info/rpmsrate''; this file manages the relative importance of the files, and thus their installation or not. To modify the code of stage2, use "misc/mdkinst_stage2_tool install/stage2" to generate "install/stage2/live". When you are done use "misc/mdkinst_stage2_tool install/stage2" again, the "rm -rf install/stage/live". See below for information about these files. ******************************************************************************** * FILES ************************************************************************ ******************************************************************************** First here are the different things needed : media/media_info/hdlists description of the available install media. format is one line for one medium as <hdlist_name> <rpms_directory> <description> <hdlist_name> should be match regexp /hdlist\S*.cz2?/ for example (two cd install) you get hdlist1.cz Mandrake/RPMS1 Boot CD hdlist2.cz Mandrake/RPMS2 Extension CD media/media_info/hdlist*.cz table of rpm's headers, referred by ``hdlists'' their contents can be listed using ``packdrake -l <hdlist_file>'' or or ``parsehdlist <hdlist_file>''. ! Need to be remade when media/main changes (with ``gendistrib'') ! media/media_info/depslist.ordered for each packages, tell which package it depends on. Also contains the size for some (obscure) bloody reasons. ! Need to be remade when media/main changes ! (with ``gendistrib --noclean --distrib .'') media/media_info/compssUsers media/media_info/rpmsrate ranks and classify packages, so that the installer will know which ones to install. format is : <intern_group> <level> <packages> where <intern_group> is a symbolic name used in media/media_info/compssUsers* files, and <level> defines importance level as described below : 5 must have 4 important 3 very nice 2 nice 1 maybe by default (for non expert), group selects packages for level 4 (important) and 5 (must have). export mode add 3 (very nice) level. other level (below 2) can only be selected using individual package selection. install/stage2/live live system used on certain installs. See ``Ramdisk or not'' below for more. install/stage2/mdkinst.clp for the compressed loopback of install. generated from install/stage2/live tree using misc/mdkinst_stage2_tool install/stage2/rescue.clp rescue ramdisk. create_compressed_fs iso file this is the ramdisk loaded when typing rescue on boot prompt. install/images/*.img floppy boot images to use with DrakX. Use: - cdrom.img for cdrom install - network.img + network_drivers.img for ftp/nfs install (non-pcmcia devices) - hd_grub.img for hard-disk install (see http://qa.mandriva.com/hd_grub.cgi) - pcmcia.img for pcmcia install (see ``PCMCIA install'' below for more) install/images/boot.iso iso image to burn enabling any install (cdrom/hd/nfs/ftp) Boot from cdrom: - boot.iso : iso image to burn Boot from hd (esp. usb key): - all.img : fat16 image to dd on a partition (hint: sda1) - it seems some bioses don't use the code on MBR (sda), or at least skip it when it's blanked (eg: "dd if=/dev/zero of=/dev/sda bs=1 count=446") - some bioses need it. I had some luck using dd if=/usr/lib/extipl/aldebaran.bin of=/dev/sda (install package extipl first) Boot from network: - all.rdz + vmlinuz via pxe Boot from floppy: - cdrom.img : to install from a cdrom (but not a usb drive) - network.img + network_drivers.img : to install from network - hd_grub.img : to install from hd dd for windows: http://uranus.it.swin.edu.au/~jn/linux/rawwrite/dd.htm ******************************************************************************** * logs ************************************************************************* ******************************************************************************** During install, a lot of interesting stuff can be found in different places: in consoles and in files. To switch to console 2 for example, do Ctrl-Alt-F2 from the X install. - alt-F1: the stdout of the install. Not very interesting stuff - alt-F2: simple shell. Quite a lot of commands are available but as they are written in perl (for space), they do not handle the very same options as normal. After install, you can do ``chroot /mnt'' to see your system just like after rebooting. ``rpm -qa'' works for example. - alt-F3: a lot of interesting things. Be carefull, some ``ERROR'' messages are not interesting. - alt-F4: kernel's place. aka the output of dmesg. - alt-F7: the graphical install lives there - command "bug" puts on floppy lots of interesting stuff. - /tmp/stage1.log: same as alt-F3 part when stage1 run (e.g. actions before graphical install really begins) - /tmp/ddebug.log: (nearly the) same as latter alt-F3 part - /tmp/syslog: same as alt-F4 - /mnt/root/drakx/ddebug.log: at the end of each step, DrakX tries to backup /tmp/ddebug.log to /mnt/root/drakx. Available only after mounting of /. - /mnt/root/drakx/install.log: the log of the installation (or upgrade) of the rpms (just like rpm's /mnt/tmp/(install|upgrade).log) - /mnt/root/drakx/auto_inst.cfg.pl: a kickstart file generated at the end of each step. Can be used in 2 ways: kickstart install or ``defcfg'' install. Hopefully you know about kickstart. ``defcfg'' is a way to customize the default values in install. For example, French can be the default language with a qwerty keyboard, the auto-partitionning partitions can be changed, the default user class can be set to developer (!)... ******************************************************************************** * po translation files ********************************************************* ******************************************************************************** DrakX uses .po files for its translation. A script takes the different strings out of the .pm files. It generates the DrakX.pot file which contains all the english strings to translate. ******************************************************************************** * PCMCIA install *************************************************************** ******************************************************************************** If the media you use to install is a pcmcia device, use the pcmcia boot disk. ******************************************************************************** * modules ********************************************************************** ******************************************************************************** Modules can be found in at least 2 places: - in /modules/modules.mar - in /lib/modules.cz<KERNEL_VERSION_RELEASE> /modules/modules.mar is used in mdk-stage1. It contains only modules interesting for one kind of install. For example in an hd install, it contains scsi modules. For a network install, it contains network card modules. (To create, extract or view files in a ``mar'' archive, please use gi/mdk-stage1/mar/mar; this is basically an archive format meant to be minimalistic) /lib/modules.cz<KERNEL_VERSION_RELEASE> contains all modules, it is used in stage2. To manually install a module during install, switch to console #2 and type "modprobe <modulename>". The modprobe program is a perl wrapper around /usr/bin/insmod. It uses the dependencies found in /modules/modules.dep (stage1). /usr/bin/insmod is a wrapper around /usr/bin/insmod_. It just extracts the module out of /lib/modules.cz in /tmp. Then it calls insmod_. /usr/bin/insmod_ is the real prog (which you usually find in /sbin/). You need to give it the complete path. ******************************************************************************** * Making screenshots *********************************************************** ******************************************************************************** 1. easy solution: press "F2"! 2. On a test machine, make a network install, switch to console (ctrl-alt-F2), enter: % xhost+ then, on another computer: % DISPLAY=test_machine:0 xwd -root | convert - screenshot.png ******************************************************************************** * Auto install ***************************************************************** ******************************************************************************** A powerful auto-install system is available. It allows performing an install without any human interaction. To feed automatic parameters to the stage1 part (the textmode part - might not be necessary for you if you plan to do cdrom-based auto-installs, but mostly highly needed when doing network installs), please refer to ../mdk-stage1/doc/TECH-INFOS. About the stage2 part (the actual installer, at the time you're (usually) running in graphical mode), please refer to the nice documentation written by David Eastcott. Either install the package "drakx-autoinstall-doc" from contrib, or browse: http://members.shaw.ca/mandrake/drakx/9.0/HTML/ The previous document will explain you how to setup the contents of the auto_inst.cfg file. Note that you have 3 alternatives for providing this file: - from a floppy disk; use "kickstart=floppy" as kernel parameter, as explained in the document - from the installation volume itself; put the file in the "install" directory of the installation volume; use "kickstart" only, or "kickstart=filename" to specify another filename than auto_inst.cfg - specified by the network; setup your DHCP server to provide the "bootfile" parameter, this file will be used as the "auto_inst.cfg" file; in this case you also need to provide the "netauto" boot parameter In any case, if the specified file ends with -IP or -IP.pl, IP will be substituted by the IP address of the machine, when doing a network install. Might be useful so that you can control all your auto installs from your server. ******************************************************************************** * Miscellaneous **************************************************************** ******************************************************************************** > o Media access methods: nfs, ftp, http, hd, cdrom > o Stages: init, stage1, stage2 > - What exactly each stage does init loads stage1 stage1 loads stage2, from various medium type stage2 is too big to fit on a floppy, that's why stage1 exists > - How each stage relates to the various media access methods stage1 knows only how to access to the media is compiled for. It contains only the kernel modules needed for that media. For eg, the nfs/ftp/http stage1 (network.img floppy) doesn't contain scsi modules nor ide. > - How one stage terminates and another begins. i.e., How does > stage1 find, mount, and launch stage2? /sbin/init just starts /sbin/stage1, and monitors its execution; it's here to cleanly umount the partitions when stage1 or stage2 dies/finished /sbin/stage1 takes care of mounting stage2 (in ramdisk if necessary) then it execs /usr/bin/runinstall2 (thus, stage2 replaces stage1, and init then monitors stage2) > o Text and Graphic mode installers > - Architectural overview of each have a look at gi/docs/object_class.fig
