Subject: [PATCH] Add quotation marks to parse string correclty on rhel7
Problem:
On rhel7 the lvm.conf filter is generated wrongly
Root Cause:
bash-4.2 (rhel7/centos7) incorrectly splits herestrings
when combined with IFS. See [1] and [2]
Quoting the argument is a safe work-around

[2] https://bugzilla.redhat.com/show_bug.cgi?id=1196566
Closes-Bug #1425839
