Debian Lenny: / on LVM2 on dm_crypt on raid

This is just Google-fodder:

If you use the lenny (beta2) installer to setup a system which uses / on LVM on dm_crypt on raid, then the first reboot fails with something like “cannot find LVM volumes”. After a few minutes you get dumped into a busybox shell.

Fixing this for good

It seems to be that this Wiki page still applies. Thus you have to create a line in /etc/crypttab containing (in my case md1)

md1_crypt /dev/md1 none luks

and run update-initramfs -u to update the initrd.

That’s it.
