Hello HantsLUGgers
I want to make a backup drive available to users, but only in read-only 
mode.
I can do this:
    mount /dev/backupdrive /backups
    mount --bind /backups /backups-readonly
    mount -o remount,ro /backups-readonly
which has the desired effect.  (Note that --bind and -o ro can't be used 
in the same mount command.)
The tricky bit is that I want to do this via autofs.  I can't find a way 
to make autofs run two mount commands.  Its scripting feature only 
creates dynamic configuration files, which doesn't seem to help.
Does anyone have any ideas?
cheers
Chris
