yeah, that's the sensible way. I'm just always looking for ways to
make it more difficult as a learning process. For example, I recently
implemented encryption on my laptop *after* installation by jumping
through all sorts of hoops ... never had an unusable system during the
whole process. I consider it a great learning tool so that if I ever
have something truly go south then I understand pretty well how it
all works and can hopefully rescue it.

yes, the laptop will be a test bed before the real machine gets

one thing I just came up with is doing a find for all debs in
/var/cache/apt/archives that contain i386 in the filename. THose will
all have to be replaced... I'm sure a simple scripted wget would get
that done...
