Even better would be writable snapshots for that:
- make a snapshot of (everything where the install writes to
- install the program
- test it on the snapshot
- junk the snapshot if the install is bad
and, of course, you might want to migrate changes from the
snapshot to the original FS (or vice versa). That however
is a second feature. Until then you'd have to do the install
all over again -- once we actually get writable shnapshots.
