It seems that this is not only true for nullfs but also for ufs and zfs:
# mkdir -p /tmp/testdir/{ufs,zfs}
# mount /dev/ufs/test /tmp/testdir/ufs
# zfs create -o mountpoint=/tmp/testdir/zfs pool/test
# touch /tmp/testdir/zfs/testfile
# touch /tmp/testdir/ufs/testfile
# ls /tmp/testdir/ufs
testfile
# ls /tmp/testdir/zfs
testfile
# mkdir /tmp/testdir2
# mount_unionfs /tmp/testdir2 /tmp/testdir
# ls /tmp/testdir/ufs
# ls /tmp/testdir/zfs
#
Submounts are not accessible if a unionfs is mounted on a directory.
Regards,
Romain
