Inside fstab.jail this will allow read-only permission
At the command-line this works for read/write permission . . .
but it don’t work for read-only permission …
What is the sequence that can be used to mount and umount a directory with read-only permission at the command-line, or is it even possible?
/usr/src /myjails/Database1/usr/src nullfs ro 0 0
mount_nullfs -o /dev/ada0s1f /usr/src /myjails/Database1/usr/src
mount_nullfs -ro /dev/ada0s1f /usr/src /myjails/Database1/usr/src
