I'm fairly new to LUKS, but are your sure about ext3? I use ext2
throughout and so far, so good.
Using one identifier "home" in multiple contexts would confuse me, and
could be confusing some piece of software. I try to use unique and
meaningful identifiers everywhere to keep things straight (especially
with multiple drives, LUKS, and LVM).
Here is an external drive that holds backup and archive images. Note
the ext2 partition and ext2 file system, and related names /dev/sda1,
/dev/mapper/sda1_crypt, and /mnt/sda1_crypt:
