Enable execute on partition mounted with noexec

The example situation:

• Wish to execute a bash script at /var/foobah/myscript.sh
• But /var/ has been mounted using noexec via /etc/fstab.
• How to solve? Using bind mounts.

Firstly, create a directory to hold script(s), located somewhere that has exec rights, then create the target directory on noexec partition:

$ mkdir --parents /opt/magnetik/foobah
$ touch /opt/magnetik/foobah/myscript.sh
$ chmod u+x /opt/magnetik/foobah/myscript.sh
$ mkdir /var/foobah

Now add following line to /etc/fstab:

#
/opt/magnetik/foobah /var/foobah none bind

Finally, remount and confirm change:

$ mount -a
$ mount

Done!
