Hi again lineman (and list).
Just for another data-point, I have just now finished
upgrading my laptop, with the dm-crypt-encrypted hard
drive, from etch to lenny. There were several minor
issues with packages, but the crypto part worked fine.
(Anticipating doing this myself is part of why I
was following this thread...)
I *do* see the "Driver 'sd' needs updating" message,
but my system boots, so that's apparently unrelated.
My /etc/fstab file doesn't use UUIDs, it lists the
device-mapper names of all the devices, and it works.
This shouldn't matter in any case for the root FS, it's
mounted before /etc/fstab is read, and the device name
is taken from the kernel args.
I tried booting with the "break" boot option, which drops
you into the busybox shell at the init-premount step, and
tried to see if I could manually set up the crypto, but it's
a bit complicated, and relies on environment variables which
are set for the scripts, but apparently not set in the shell.
One thing you *can* do easily is, boot with the "break"
option, and from within the resulting shell, run
/scripts/init-premount/udev, which will create all the devices.
You can then do an "ls" in /dev, and see if the relevant
hard drive partition (/dev/sda5, in your case) is are present --
this tests the udev step pretty directly.
Hope this helps.
