Public bug reported:
The system fails to boot properly if using random encryption keys for eg. tmp
or swap partitions.
I have set up everything according to the man pages of crypttab eg;
cswap /dev/sda6 /dev/random swap
ctmp /dev/sda7 /dev/random tmp
When booting the system it "hangs" on "Starting early crypto disks..."
By pressing control-break a few times the system continues to boot fine.
Replacing the /dev/random with generated key files everything works great
without the "hang"
I'm guessing it's due to the same warning I am getting when trying to use
/dev/random as key file when running cryptsetup on a test partition once the
system has booted.

[EMAIL PROTECTED]:~$ sudo cryptsetup luksFormat /dev/loop0 /dev/random
WARNING!
========
This will overwrite data on /dev/loop0 irrevocably.
Are you sure? (Type uppercase yes): YES
Warning: exhausting read requested, but key file is not a regular file,
function might never return.

Well.. it's true it never does return. I am pretty sure this worked in
Gutsy. Please let me know if I am missing something terribly obvious.
