I think it's more nice to have the folder ready to be mounted in case
the admin would need to do some maintenance. I don't really like the
temporary thing...

I think this is what I'm going to do yes. I think it's not convenient,
but if it's the only way...

It's mounted for the time of the setup of the VM, and that's about it.
But very often, for maintenance reasons, the admin would have to mount
it to access the customer's VPS files. Currently my setup script also
modifies /etc/fstab so it can be directly mounted with the correct
options (and save time in case of a disaster recovery).
