Doc Type:	Bug Fix
Doc Text:	Cause: Previously ktune didn't handle the /etc/sysctl.d directory nor it didn't support more multiple files with sysctl settings. Consequence: The /etc/sysctl.d settings whis is installed by several packages like libvirt was ignored. Fix: The ktune code and profiles were modified. Result: Now all the sysctl settings under the /etc/sysctl.d directory is loaded and then the /etc/sysctl.conf is loaded. Also the user can now specify multiple sysctl files (wildcards are also supported) to load in the tuned profiles.

Description Axel Thimm 2013-05-05 02:52:36 EDT

Description of problem:
sysctl configuration under /etc/sysctl.d is ignored when tuned applies SYSCTL_POST (usually just /etc/sysctl.conf)

Version-Release number of selected component (if applicable):
tuned-0.2.19-11.el6.1.noarch

How reproducible:
Always

Steps to Reproduce:
1.Installed tuned
2.Pick a profile
3.
 
Actual results:
/etc/sysctl.d entries are ignored

Expected results:
/etc/sysctl.d entries should be respected

Additional info:
/etc/sysctl.d is already used by libvirt and vdsm

A crude fix is the following hack into the initscript:
