[Bug 706553] Re: geninitrd fails if softraid partition (mdXpY) used as rootfs

[Arkadiusz Miśkiewicz]

Are you sure that you use geninitrd and mod-md.sh from svn trunk? Here
with your mdadm --scan... output works fine:

geninitrd: Finding RAID details using mdadm for rootdev=/dev/md0p1
geninitrd: md: found rootdev=/dev/md0p1 on device /dev/md0 with devices list /dev/sda1 /dev/sdb1 /dev/sdc1
