[Bug 601380] Re: update-initramfs "missing md root"

[Aryeh Gregor]

I also hit this bug.  We installed Ubuntu 10.04 fresh on LVM with no
RAID, then I set up RAID and moved the root filesystem there using
pvmove.  Then when I tried running update-initramfs -u -k all, I got:

$ sudo update-initramfs -k all -u
update-initramfs: Generating /boot/initrd.img-2.6.32-25-server
mkinitramfs: missing md root /dev/mapper/lvm_Boot-root /sys entry

MODULES=most is already set in initramfs.conf.  I'm afraid to reboot
now.
