Would also be an option - less fine grained, but also less clutter and
less work to set up. I'll wait or some more feed back (also regarding
the naming) and then send a v2, unless a better option comes up.

In the long term, it would IMHO make sense to move to a different way of
configuring bind mount points altogether - set them up as a (special?)
storage that contains a whitelist of source paths and mapping to nodes
(only possible as root) and then allow regular users to configure them
in the GUI. It might also be nice to implement some kind of "shared
folders" feature for the VMs along with that (could reuse the "storage"
definition) - but that's a different can of worms.
