Cloning to RHEL.

+++ This bug was initially created as a clone of Bug #887017 +++

The sub-config files located in the folder '/etc/sysctl.d' are not being loaded on bootup.  See below for example.


<after bootup>

[root@desktop ~]# cat /etc/sysctl.d/libvirtd |grep -v ^#
fs.aio-max-nr = 1048576

[root@desktop ~]# cat /etc/sysctl.d/postgresql 
kernel.shmmax=446668800

[root@desktop ~]# sysctl -a |grep fs.aio-max-nr
fs.aio-max-nr = 65536

[root@desktop ~]# sysctl -a |grep kernel.shmmax
kernel.shmmax = 33554432

As you can see, the values are not proper after the system boots.  If i manually set the values to the desired setting via the sysctl utility from the CLI, then all is well.

Version is Fedora 18 Beta with current patch level as of today (12/13/2012). see below for actually version number of initscripts....

[root@desktop ~]# rpm -qf /etc/sysctl.conf 
initscripts-9.42.1-1.fc18.x86_64

See 'man sysctl.d' - files should end with '.conf'.

Ah, yes... I guess i should file this under the *libvirt-daemon* package then.  The libvirtd file under the /etc/sysctl.d directory (in the libvirt-daemon pacakge) does not have the .conf extension and it's settings are not being applied.

# rpm -qf /etc/sysctl.d/libvirtd
libvirt-daemon-0.10.2.2-1.fc18.x86_64

# cat /etc/sysctl.d/libvirtd |grep -v ^#
fs.aio-max-nr = 1048576

Reading that man page, it sounds like libvirt should be installing into /usr/lib/sysctl.d/libvirt.conf, not /etc/sysctl.d/ - so it is more than just a wrong suffix, but a wrong location.

--- Additional comment from Bill Nottingham on 2012-12-17 12:26:29 MST ---

/etc will work, but /usr/lib/sysctl.d is preferred for system-distributed configurations.

--- Additional comment from Nick Nachefski on 2012-12-18 11:55:37 MST ---

I guess that just leaves the matter of adding the proper '.conf' suffix to the file then.

In the spec file, how does one guarantee that the file will be installed into /usr/lib/sysctl.d, even when %{_libdir} is /usr/lib64?

--- Additional comment from Kay Sievers on 2013-01-04 14:14:48 MST ---

/usr/lib/<pkgname>/ has nothing to do with %{_libdir} or multi-lib.
It is always:
  %{_prefix}/lib/<pkgname>
and treated as the "application private directory" which is the same
for all architectures and systems.

%{_libdir} is for shared libraries and almost nothing else.
