| |
Since circa 3.5, we've had dozens of reports of people hitting this warning. Forwarded reports have been met with silence, so just remove the warning if no-one cares.
Example reports: https://bugzilla.redhat.com/show_bug.cgi?id=797687 https://bugzilla.redhat.com/show_bug.cgi?id=867174 https://bugzilla.redhat.com/show_bug.cgi?id=894865
