  at one time i was thinking that i could put my entire system
on git, and then i found out that git didn't like it if you had
subdirectories with git in them so that was as far as i got 
with that idea.

  a rolling snap shot of the entire system should let you
revert changes, but somehow you would need to figure out the
differences you'd want to keep from those you didn't.  since
that can be a non-trivial task for many people that is 
probably why not many people do it.

  i installed timekeeper (i think it was) to try that out and
after a few days decided that it took up too much space for 
what i really wanted and needed so i went back to my previous
method (a once in a while full back up and other select backups)
and the various safer booting options (including from a USB
stick) with a stable version of Debian on them.
