Then add jail_mount_enable="YES" (applies to all jails) or jail_named_mount_enable="YES" (just for that jail) /etc/rc.d/jail will mount the contents of /etc/fstab.named at jail startup time, which is well after all the zfs mounts have happened. See rc.conf(5) for details. Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil.
