This is meant to install a new BE (boot environment) given a fully built world/kernel. In addition to installing world and kernel in the new BE, it also automatically performs /etc updates (using etcupdate or mergemaster) and package updates (using pkg). Because this process is performed in a new BE, it reduces the need for a second reboot. It also means a reboot into a partially updated system (due to install or hardware failure) can't happen. Inspired by and similar in function to Solaris/illumos-style upgrades.
