If you're paranoid enough to encrypt the disk, I'd strongly advise not
to use swap at all - buy a few G memory, that should be enough. (Or, if
you're desperate, encrypted swap. But I guess your system won't be
usable anymore.)

This is just imho, of course.=20

The swap problem persists even if you don't encrypt partitions, but only
certain files - perhaps script something to switch off swap before
editing these files and switch swap back on when you're finished or
something like that. wiping the swap partition before shutdown is
certainly a good idea, I'd say 'dd if=3D/dev/zero of=3D/dev/swappartition'
should usually suffice. The problem is just: are you sure that your
enemy will not come while your computer is running and the swap
partition filled with useful data? Have you got time to shut the
computer down and let it wipe the swap partition?

till I tell you.  I meant 'there's a nice knock-down argument for you!'"

tone, "it means just what I choose it to mean -- neither more nor less."
	"The question is," said Alice, "whether you can make words mean
so many different things."
	"The question is," said Humpty Dumpty, "which is to be master --
that's all."
