On my system: $ zfs list | grep empty zroot/var/empty 14K 239G 14K /var/empty $ zfs get readonly zroot/var/empty NAME PROPERTY VALUE SOURCE zroot/var/empty readonly on local So this is necessary before you run freebsd-update: # zfs set readonly=off zroot/var/empty Obviously, set readonly=on after freebsd-update has finished: # zfs set readonly=on zroot/var/empty Regards Andrew
