Description OpenShift BugZilla Robot 2021-09-15 18:58:11 UTC

+++ This bug was initially created as a clone of Bug #2004508 +++

Description of problem:
TuneD recently introduced (https://github.com/redhat-performance/tuned/pull/375) changes that break certain TuneD profiles can be parsed.

Version-Release number of selected component (if applicable):
NTO 4.9.

How reproducible:
Always.

Steps to Reproduce:
Create a TuneD profile with comments not starting at the beginning of the line, such as:

[selinux]
avc_cache_threshold=8192                      # some comments

or
[sysfs]
/sys/bus/pci/devices/0000:00:00.0/power/control=on

Actual results:
Profile fails to apply correctly.

Expected results:
Profile applies correctly.
