This is what I'm trying to prevent; that they might accidentally damage the recovery.
What about limiting the
permissions in PCLOS?
Unfortunately, the partition is NTFS, so I can't just use permissions.
However, you just gave me an idea: I'll try to limit the access in fstab (use the "read only" option). I'll try right now.
EDIT: That did work in some way. Using the "noauto" and "ro (read only)" options in fstab causes the partition to be locked: only root can mount it, and even when mounted it's read only.
This would do at the moment. However, if there was a way to actually
hide a partition from Linux, that could be useful under certain applications. I'll leave this issue open for the moment.
