I really didn't prepare for lvm. I never used lvm before this so had no
idea of lvm before.

Snapshots sound like an awesome idea.

I would like to do a configured base install, create a snapshot, and modify
(fork), the base for different things.

With 20/20 hindsight. The default doesn't seem to have room. What are
different solutions other debian/lvm users have used?

Thanks
Forest
