If you use ZFS, it's possible to take snapshot, then install new ports, then if something blows up, you can rollback. With UFS, it's still possible to take snapshot but rollback is not atomic. If you use portmaster, it can save packages (I think portupgrade can do it too). But this approach depends on the fact that the port is well written, and is not atomic in terms of package set. BTW. Speaking for 8.1, it's past EoL, please consider upgrading to a supported release.
