Hello list,
I've changed my RAID and LVM configuration and need to modify the respective commands in the /init of my initrd.
I made those changes by decompressing and extracting the cpio archive, editting the init script (add a couple lines for mdadm, changed the activated volume group name), rebuilt a cpio archive (using the correct "-c"/"-H newc" SVR4 format) and fed it back through gzip (max compression), then I just moved aside the old initrd, replacing it with my new one:
mkdir /boot/tmp cd !$ gzip -dc ../initrd-<version> | cpio -id vi init find . -depth -print | cpio -oc | gzip -9 > ../initrd-<version>.new cd .. mv initrd-<version> initrd-<version>.orig mv initrd-<version>.new initrd-<version>
The kernel now panics (paraphrase) "can't find /init".
It does not do this if I restore the original initrd.
I have not changed the name of the initrd, filenames match grub.conf and grub's boot menu, etc. I have done this type of modification successfully in the past, but only changing a single character in /init.
So, it appears the kernel is not using my use initrd. Perhaps it is not prepared correctly (file magic for both new and old initrd files suggests they are the same, however)? Is grub involved somehow? Perhaps it can't find my new initrd?
/boot is on a raid1 partition, ext2fs. Grub knows about this, and the system used to boot without problem.
Any advice?
Thanks, Richard
