[Pkg-cryptsetup-devel] Bug#397887: resume support renders system
unbootable

Package: cryptsetup
Version: 2:1.0.4-4
Severity: important
As of late, cryptsetup figures out what swap device I need to resume
from disk and tells initramfs to also initialise that device even
before root is brought up.
The problem is quite simply that some of us have previously
configured the swap device with a random passphrase, or a keyfile
stored somewhere in /etc. Now, all of a sudden, we're expected to
enter the key during initramfs? I am sorry, I cannot remember 2048
bytes of key material, nor would I remember what random string the
kernel used to set up the swap device before the latest cryptsetup
upgrade.
My crypttab says
cr_hda2 /dev/hda2 /etc/keys/hda2.luks luks
cryptsetup should ensure that /etc/keys/hda2.luks is available as
such during initramfs. If the key is specified as /dev/urandom,
cryptsetup must react differently and prompt the user for a new,
static passphrase.
