If you're up for doing something a bit trickier, consider building a
set up something like this:
Follow the instructions in the jail(8) man page for setting up
a second copy of your system. This is just to act as a
scratch system which you can trash with impunity, without
rendering your whole system unusable.
Within the jail, set up a baseline system as you want it, then
use union mounts to overlay your jailed system with empty
filesystems. Now as you compile and install new stuff within
the jail, the modifications will go into the overlay
directory, which you can examine independantly. Should you
wish to wipe out your changes, simply clear out the overlay
directory. See the mount_union(8) man page for details, but
note this warning:
BUGS
THIS FILESYSTEM TYPE IS NOT YET FULLY SUPPORTED (READ: IT DOESN'T WORK)
AND USING IT MAY, IN FACT, DESTROY DATA ON YOUR SYSTEM. USE AT YOUR OWN
RISK. BEWARE OF DOG. SLIPPERY WHEN WET.
Cheers,
Matthew
