Using ZFS to rollback to clean installation?

Hi!

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.
 
How did you create snapshots, and how did you rollback? How did you install FreeBSD?

Without being concrete about steps you did, it's hard to give a concrete answer.
 
Those are the commands, if you have only one filesystem, i.e. everything under /.
Otherwise check man pages and -r switch.
