This depends on whether it's the default setting or not.  If it's not,
it definitely does (just the burden of figuring out what the heck is
wrong is already significant for many users).

I second that.  kFreeBSD disk encryption supports generating
one-time keys, which works well for swap:

  geli onetime -s 4096 /dev/something
  swapon /dev/something.eli

For that we're missing a port of "geli" utility, figuring out some init.d
magic that would replace (or integrate with) "swapon -a", and
integration with D-I to set the whole thing up.

I don't have time to work on this myself. Unless someone else does,
I'd still recommend adding the SUID bit as a temporary solution.

What do debian-bsd folks think about this?

P.S. I suggest you update that FAQ ; -)
