"zfs mount" shows just what is mounted. "zfs list" shows data sets from imported pools no matter if they are mounted at the time or not. The MOUNTPOINT column is a property indicating where a mount would show up by default. Some may be mounted at the time and others may not be. Your later: QUOTE bectl list BE Active Mountpoint Space Created 13.1-RELEASE_2022-08-31_153934 - - 498M 2022-08-31 15:39 default NR / 14.6G 2022-05-12 09:50 END QUOTE indicates only one of the 2 is mounted: it shows "/" only for boot environment active mounts. (Having both mounted would normally be obvious: things would not be operating like normal at all.) It is possible to replace the "/"s that "zfs list" shows with "none". In fact there is a page that recommends such: https://wiki.freebsd.org/BootEnvironments under "Pool Layout/Design". Part of the point being that accidentally ending up with both zroot/ROOT/default and zroot/ROOT/13.1-RELEASE_2022-08-31_153934 mounted would not be a good thing and the way things are in your environment makes it easier to end up with such accidents. (But having both those "/"s is a normal default configuration despite this.) =3D=3D=3D Mark Millard marklmi at yahoo.com
