Once you try it, you're never going back. Snapshots are made for things like system administration. Upgrade borked your system? Just rollback.

Want to use the last version of your firewall config? I wrote a utility you might like to try, httm[1], which allows you to restore from your snapshot-ed unique versions.

If you like ZFS, then trust me you have to have ZFS on root.

Had you previously done a Show HN on this? I feel like I saw it once before.

ZFS on root is really amazing on FreeBSD and the advantage is that you can snapshot your boot drive.

have a look at Boot Environments. It really is amazing.

Yes I know, bectl. I use it.

I just didn't want to mention it because the discussion was mainly about Linux. But FreeBSD has a really strong toolchain for this indeed.
