I have a loadable module that I wish to insert before the init process is spawned. I can certainly do it in any of the run levels..i have tried that successfully, but is there a way where the module can be inserted before the init process is created, ie somewhere when the kernel is being loaded and before kernel creates init process..

how about initrd..is there a way to add a module here..I have come across someting to modify /linuxrc but i could not locate the file...

Linuxrc is INSIDE initrd, to see it: cp /boot/initrd /tmp/initrd.gz gunzip /tmp/initrd.gz mount -o loop /tmp/initrd /mnt less /mnt/linuxrc But there is an easy way to put your load statement and all its dependencies into linuxrc. Add it to /etc/sysconfig/kernel INITRD_MODULES and run mkinitrd eg: vi /etc/sysconfig/kernel INITRD_MODULES="e100 reiserfs " then run: mkinitrd Your module will be loaded during the initrd phase of booting before root is even mounted. This will work fine as long as your module loads cleanly. If it doesn't you might be in trouble. There is another parameter I haven't messes with yet called: MODULES_LOADED_ON_BOOT Might be just what you are looking for. Good Luck, michaelj PS: linuxrc in Suse9.1 is much more complicated than the 3 liner in Suse8.2 Oh well, that's progress. -- Michael James michael.james@csiro.au System Administrator voice: 02 6246 5040 CSIRO Bioinformatics Facility fax: 02 6246 5166
