Comment 2 for bug 1710239

This is a custom config that we set on disk_root.

I think this actually should be filed against monitoring-plugins-basic package, as it's the .deb that provides /usr/lib/nagios/plugins/check_disk.

I know that check_disk ignores things like sysfs and similar...it should also ignore loop mounts (whether snap or iso loops, or otherwise, perhaps unless it's a valid read/write fs type)
