I will confess that I don't fully recall what I did when I set this all up, but I was given an option to encrypt my home directory, and I took it.

Lately, I've started seeing an occasional error on boot: my machine complains that it can't boot /dev/mapper/cryptswap1.

For a while it would just hang, but after a recent update I noticed it offering me the option to hit esc and drop into a shell to resolve the problem. Actually hitting esc, though, just lets me proceed to the login screen.

The whole thing is (not surprisingly) kind of nervewracking because I don't know what the problem is.

I'm on Karmic.

Here's my fstab:
