bind mounting read-only using fstab?
Solution 1:
I found the answer which works for me on debian. It's from:
http://www.sagui.org/~gustavo/blog/fedora/read-only-bind-mount.html
/source/dir /destination/dir none bind 0 0
/source/dir /destination/dir none remount,bind,ro 0 0
If that doesn't work, you could do put the mount commands in rc.local. Which is ugly.
