it's a mountpoint for that file system.

on my main devbox, when i boot -current, /altroot is the -10 install, and
when i boot -10, /altroot is the -current install.

on an arm64 server, i have /altroot being the emmc back up boot, when the
nvme is broken, and i tend to update the emmc only infrequently.

i otherwise use it as a randon other /mnt ...
