I didn't read it, but if this encryption crypts a complete partition,
then I'd like to recommend to better use a crypted loopback mounted
file. The reason is backup: In the latter case you can simply compress
the crypted container and back it up - it is still crypted.
I did it this way some time ago and found it very convenient.

Put it in a tarball preserving all file attributes (ownership and other
flags) and untar it into the crypted container after mounting it.
