Resizing the partitions during installation in the /target chroot works.

OK. I read the manual (again) and do find a short note that lxde should
be used for LTSP, but what you write here sounds like more than a simple
recommendation. Maybe the manual should be clearer about that (the note
is also very well hidedn, IMHO - the paragraph is about changing the
desktop environment from the default, so I'd skip reading it if I don't
care changing the default).

OK.

But really - we should absolutely test the installer as it comes out of
the box. I really think most people will want to use it that way.

Oh. Sorry, I missed the bit about the differing archs!

Great!
