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.
