When I first installed my FreeBSD system, I created a ZFS snapshot of the clean installation. I then installed a couple of applications and created a few files, and then attempted to rollback to the clean installation. But it did not work. The applications I installed are still there (nano for example).
Is there a way to remove all new files that have been created, as well as rolling back the files that have been modified? A complete revert to the earlier state, pretty much?
Thanks in advance.
