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. -To add a new language, you just have to add it to lang.pm (if it's not there -already) and put the .po in the perl-install/po directory (see ``Ramdisk or -not'' to know if you have to regenerate the mdkinst_stage2.gz) - -******************************************************************************** -* PCMCIA install *************************************************************** -******************************************************************************** -If the media you use to install is a pcmcia device, use the pcmcia boot disk. - -******************************************************************************** -* Ramdisk or not *************************************************************** -******************************************************************************** -The DrakX install is much bigger than the newt one. So the ramdisk which was -used is getting big, and costs a lot in memory -(eg: the mdkinst_stage2 is 14MB - 23/09/99) -(update! now size is 21MB - 24/01/01) -(update! now size is 19MB - 26/04/01) - -| | newt | DrakX -|-------+---------+---------------------------------------------------------- -| nfs | live | live -| ftp | ramdisk | ramdisk -| http | ramdisk | ramdisk -| hd | ramdisk | live if Mandrake/mdkinst/usr/bin/runinstall2 is a link, -| | | ramdisk otherwise -| cdrom | ramdisk | live if memory < 52MB, ramdisk otherwise - -Where ramdisk is needed, if detected memory is below the limit allowed for -ramdisk (maintained in file gi/mdk-stage1/config-stage1.h; currently 52 Mb), -a failure dialog will be printed explaining that there is not enough memory -to perform the installation. - -When i say live, it means that the stage1 will *mount* the -Mandrake/mdkinst and use it that way. - -The ramdisk is used in place of the live in some cases. This ramdisk is filled -with mdkinst_stage2.gz - -For cdrom install, the ramdisk is used to speed up things (access time is quite -high on cdrom drives) - -For pcmcia, it depends on the type of install. - - -******************************************************************************** -* modules ********************************************************************** -******************************************************************************** -Modules can be found in at least 2 places: -- in /modules/modules.mar -- in /lib/modules.cz - -/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 contains all modules, it is used -in stage2. - - -To install a module, use modprobe which is in /usr/bin. It's 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 - -******************************************************************************** -* 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, on 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 -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 -/sbin/stage1 takes care of mounting stage2 (in ramdisk if necessary) - then it runs /usr/bin/runinstall2 - -> o Text and Graphic mode installers -> - Architectural overview of each - -have a look at gi/docs/object_class.fig - - -******************************************************************************** -* OEM ************************************************************************** -******************************************************************************** -> I am a system OEM in Bangalore,India selling systems bundled with -> Mandrake Linux. The problem is that with every system I sell, I need to -> install & configure the system which takes HOURS!. Can I do a diskcopy -> instead? -> -> Please Help. This is a major bottleneck for me. - -many solutions: - -- make an install on drive hdb, then : - dd if=/dev/hdb of=/dev/hdc - but you should make sure the hardware is *REALLY* identical. - -- try the oem feature - 3. - burn a cd out of *latest* cooker or 8.0 and above. - - boot on it telling "oem" to syslinux - !! it will destroy every data on the harddrive or - resize (or use free space) if *ONLY* one fat partition is defined !! - - you now have a very automated install matrix - (duplicate it with "dd if=/dev/hdb of=/dev/hdc bs=1M count=730") - - put the harddrive in the oem box, the user will now have an *very* automated - install, just asking the root password and user password, and some other - question according its hardware. - - 4. just like 3. but you may have to mount /cdrom after typing rescue on - syslinux prompt (oem script do it automatically if a automatic boot nfs - network has been done as server is known). under /cdrom may be anything - as long as it provides an installation tree of Mandrake Linux. - after that run oem script by typing "/etc/oem -f" for normal installation - or "/etc/oem -f server" for server installation (normal with server installed). - - 5. (just like 3. without burning a cd, doing the first part by hand) - have a look at the /etc/oem script on the rescue and do it by hand... - - -cu Pixel, fpons. - - -comments: -1. maybe copy unnecessary things -> take too long - solution -> use bs=8k count=xxxx -2. kernel_reread can be found on the new rescue, source is also at end of this -mail. This solution works with one partition. Can be easily enhanced to many -primary partitions... For extended partitions, more complicated, but not much :) -3. has just been added in latest cooker. It may still have some pb. The main -current limitation is IDE only, though it can be fixed easily for special cases. - --------------------------------------------------------------------------------- -#include -#include -#include - -void die(char *msg) -{ - perror(msg); - exit(1); -} - -void kernel_read(char *dev) -{ - int fd; - if ((fd = open(dev, O_RDONLY)) == -1) die("can't open device"); - ioctl(fd, BLKRRPART, 0); - close(fd); -} - -int main(int argc, char **argv) -{ - if (argc != 2) { - fprintf(stderr, "usage: kernel_read_part \n"); - exit(1); - } - kernel_read(argv[1]); -} -- cgit v1.2.1
