Thanks for information.
We use http://grml.org/files/devel/create-scsi-mod-file.sh for generating the scsi-modules.txt file.
hmm. the fusion mpt driver resides in a different location (/lib/modules/$(uname -r)/kernel/drivers/message/fusion) so you have to add this directory to the 'find'. but then again, the simple dependency logic does not work here because there are multiple dependencies and modinfo prints them in random order (for mptsas.ko to load you need to load mptbase.ko and mptscsih.ko in this order). modprobe would be cool here ... any reason not to use it?
modprobe of busybox was/is too broken. :( But when switching to the initramfs approach we shouldn't have to deal with that any further.
Excellent. Thanks a lot for sharing your patches! I'll take a closer look at them. Regarding the mdadm stuff I hope to be able to use live-initramfs in the near future which should give us more options for mdadm/lvm/... out-of-the-box in the initrd/initramfs part of booting.
this sounds good. recent kernel/initramfs combinations are really powerful and flexible regarding the device of the root filesystem. for which release is the live-initramfs transition planned?
Depends on the progress of development in the next few weeks.
If we have a grml 1.1 release quite soon, the initramfs-approach might hit 1.2, if we "delay" the 1.1 release some further weeks it might be part of 1.1 already. (I expect to take a closer look at live-initramfs at this weekend at Froscon - see http://www.mail-archive.com/grml@mur.at/msg01328.html for details.)
