Add quotation marks to parse string correclty on rhel7
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
