Just did this. Installed cryptsetup package. Created the entry in
crypthomefedora         UUID=<uuid here>       none luks

Created the relevant line in /etc/fstab:
/dev/mapper/crypthomefedora /media/homefedora  ext4 defaults  1 2

Now when I boot into Debian, it asks for the password. I enter it and it
continues to boot. I am able to read F13's home mounted on
/media/homefedora when I am in Debian.

I have started with encrypted partitions only yesterday when I installed
F13. So this encrypted hard disk stuff is all new to me. I appreciate
your comments. I will look into using a USB flash memory to store my
keys. I agree regarding the disadvantage of having the keys on the hard
disk itself though.
