update-initramfs "missing md root"

initramfs-tools version: 0.92bubuntu78

I upgraded from Ubuntu 8.04 (LTS) to 10.04 (LTS). After upgrade I needed to change MODULES=dep in
/etc/initramfs-tools/initramfs.conf
(because my BIOS is so old that with the new Ubuntu version MODULES=most takes too much space)

The I ran "update-initramfs -u" command but got the error above.

Now I cannot boot Linux until the problem is somehow solved. I appreciate any workaround!

BR,

Installed Ubuntu 10.04 to a fresh new machine and everything is ok now.

[Aryeh Gregor (simetrical+launchpad)]

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

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

[Aryeh Gregor (simetrical+launchpad)]

I deleted the file /etc/initramfs-tools/conf.d/driver-policy, which contained "MODULES=dep", and the error messages went away. (The machine actually didn't boot in the end, but I think that was a GRUB problem, not an initramfs problem.)
