Improvement: Make unmounted /srv folders not writable by default

Idea: I think it would make sense to protect the mount folders generated by omv at /srv against write access.
Background: I have scripts and rsnapshot running at night. In rare cases, disks were not mounted. Data was written to root partition instead
Solution: I can manually protect the folders (when unmounted) with chattr +i /mountpoint. They are not intended to be anything but mountpoints anyway.
(see: https://serverfault.com/questi…ted-mount-point-directory)

I think it would be a good feature for omv to do this on its own upon creating the mountpoints. What do the devs think?

Thanks for your reply, Volker.
The rsnapshot plugin from omv-extras did not check though...

Are there any downsides in making the folder immutable with chattr? It might be an additional way to protect root drive from third party plugins and custom scripts.
