Apparently I have a related problem after an upgrade from 11.10 done using
"do-release-upgrade". The troubled server has all the partitions on a software
RAID 1. With the new kernel (3.2.0-24.37) it failed to mount the root
partition, dropping to a busybox shell. After booting the ol kernel I found
there's no dmraid package installed on the server. Installing it also pulled
kpartx-boot as dependency and now I have
/usr/share/initramfs-tools/hooks/kpartx in place. update-initramfs appears to
have generated a bootable initrd this time, but I haven't had the chance to
test it yet.
Also, looking at the initrd images for 3.0.0-16-server and 3.2.0-24-generic I
found there are no dmraid & kpartx related entries in 3.0.0.16 image.
Is it perhaps worth to have dmraid & kpartx-boot as dependencies for a basic
installation? For some reason they were not installed previously. Should I file
a new bug for this? I haven't found anything similar yet.
