I did exactly that. As I keep a separate backup of additional
non-standard stuff, it worked just fine.

For the record: Recommended:

1. If you can, create a /home partition, or install a second drive
   and make it /home (or whatever structure you want for the place
   where you keep *your* stuff).

2. If you have non-standard stuff you have added, *always* keep it
   somewhere like /usr/local/src and back that up separately (eg
   to USB), or rsync it to some place else.

   I also keep things like the installation tar.gz files of the
   small amount of commercial software that I have bought in that
   directory too, so I can reinstall it from there if I need to.

3. I have a bunch of shared stuff that I use on lots of systems,
   mainly my Emacs add-ons and my DTD/Schema collection, both of
   which have standard locations in /usr/local, so they are in
   SVN repos on my server, so I can add them back to any newly-
   installed system without difficulty.

I'll pass on that, thanks :-)

Works fine. Better, in fact, as the ltXML2 utilities were giving me
problems compiling them under the 32bit distro, but under 64bit they
compiled and installed without a glitch. Some C++ weirdness.
