Public bug reported:
I upgraded to Ubuntu 14.04 via fresh install and copied my configuration
if possible.
I installed with full disk encryption, without swap partition. Now I
want to use a swap partition on a data drive, which is configured
manually after installation. I used such a setup with my old
installation but it doesn't work any more with 14.04.
crypttab:
cryptswap1 UUID=42640352-427f-4b99-99bf-9f80baca5e16 /dev/urandom
swap,cipher=aes-cbc-essiv:sha256
Calling /etc/init.d/cryptdisks reload tells me everything is ok, but
there is no swap!
I messed around with the cryptdisks.functions, see >>> log entries
below. I see no error and swapon -s reports no swap.

I found the following code in the skript, the comment says it triggers a
mountall. It is called, I checked with a logging statement. But nothing
is mounted! I found a comment about udevadm in the latest release
comments, this might have a connection.
# Rename the device from its temp name to its final name, which will
# trigger mountall
finalize_device () {
if command -v udevadm >/dev/null 2>&1; then
udevadm settle
fi
dmsetup rename "${dst}_unformatted" "$dst"
}
