[pve-devel] [PATCH container v2] start/fix #1478: add check for unsupported config

[Philip Abernethy]

Adds a check if an unprivileged container is configured to use
quota on any of its mountpoints. If so an understandable error
message is given. Ideally I'd like to catch those
configurations on the GUI, too, to avoid users just running
into it.

Applied your suggestions.
$unprivileged doesn't use // 1 any more.
Whether quotas are used will only be checked for unprivileged containers.
