What should be recommended:

To apply either /dev/random or a passfrase for the establishment of a keyfile to a swap partition?
I am thinking about a potential crash and the consequences if the swap partition has to be used for rebuild of something. Then a /dev/random or if necessary /dev/urandom would not be so good.

Unless you use swap for suspending to disk you can recreate it at boot
using /dev/random, I do not particularly like the doing that tough.
Since devices and partition have a tendency to change name under linux,
it is fairly possible that you shoot yourself in the feet for no
particular advantage.
