• ZFS boot environments with bectl: a rollback path around FreeBSD and package upgrades

  bectl clones the root ZFS dataset into a boot environment in seconds; creating one before a freebsd-update or large pkg upgrade gives an instant, loader-menu-selectable way back to a known-good system, independent of and in addition to freebsd-update's own patch/install/rollback machinery.
