Parameter 4 (fs_mntops) has ro as an additional option
/Development/FSTAB/fstab.git /fstab.git none defaults,ro,bind 0 0
I wanted to point out that the 4th field may contain optional parameters. In the above example, not shown, the base fstab.git has “default,rw,noatime” settings, and is read/write accessible, whereas the second bind target /fstab.git is read-only mode accessable.
