I created my swap partiton while installing the distribution. The
whole harddisk (laptop) is LUKS/dmcrypt encrypted. When I start up the
machine, all I have to do is to provide the proper passphrase, and all
my encrypted partitions will be unlocked, incl. swap.

As far as I can see, dracut stores the passphrase in memory, unlocks
the root-partition first, and runs the same passphrase on all the
other LUKS-devices afterwards. I can't see how this procedure could be
a problem related to swap, and why I maybe should choose a random key
over a predefined one.
