From 7b2531c135c52e9d60fdd0ae74c5957b2456631f Mon Sep 17 00:00:00 2001
From: Ed Santiago <santiago@redhat.com>
Date: Thu, 28 Oct 2021 19:04:06 -0600
Subject: System tests: enhance volume test, add debug prints

Volume test: add a sequence of stat()s to confirm that volumes
are mounted as a different device than root.

Network test: add debugging code for #11825 (dnsmasq inotify
failure in bodhi only).
