It did seem like a mess, but a good place to start with the crypt stuff,
as I could much more easily check the on disk data, and ofcourse test it
on systems without re-partitioning. :)

If that is what they prefer, then I will do that. I don't want to rattle
the cage :) Do they prefer diff's from top of source tree, or each file
induvidually from '.'?

Of course. I prefer RAIDframe to ccd generally as the raidctl program is
really easy to use. It is my intention to bring my patches from vnd/ccd
into raid as well, as they all have a similar "frame work". RAIDframe
could be abit more awkward as I (believe) it is work upon by a group,
not neccessarily in NetBSD so I would rather have their permission. Not
sure how it hangs together in those terms.
