Running "zfs set canmount=off rpool/ROOT/debian" causes the root
filesystem to be remounted read-only. I have no idea why, but that's
mostly beside the point.
I have no idea why I added these commands in the first place. The
other guides were not this way. These steps showed up in the initial
add of the Bullseye instructions.
