Hello, Greg.
  If you want to have a separate /home in case you need to reinstall
there's a tutorial for migrating to one at

One trap you must be careful not to fall into is that you must create
the first user when setting up in your reinstall with the same name as
the first user in your existing install, so that it uses the existing
home folder.  If you have multiple users, try to re-create them in the
same order or you may get permission issues.

With regards to copying your live DVD, you should be able to if you
insert it _after_ booting, when you have a running system that doesn't
depend on it.  If you get any form of autorun then, you can simply
cancel/close/etc it and copy the disc.


Version: GnuPG v1.4.9 (GNU/Linux)
