[users@httpd] mod_systemd and Apache 2.4

Looking around I see this in the default Apache 2.4.6 setup on Red Hat 7 ..

/etc/httpd/conf.modules.d/00-systemd.conf

I also see the LoadModule is uncommented ...

LoadModule systemd_module modules/mod_systemd.so


When I go here ...

http://httpd.apache.org/docs/trunk/mod/mod_systemd.html

The breadcrumb indicates that is in the version 2.5 documentation

My question is, is that module doing anything in 2.4?

If not, then commenting out the LoadModule  seems like a good thing to do to reduce the RAM usage. Correct?

Why is it uncommented by default?

Thanks

Yes.  Red Hat backports functionality all the time.  In this case, see 
the files

httpd-2.4.10-mod_systemd.patch
httpd-2.4.10-detect-systemd.patch

at http://pkgs.fedoraproject.org/cgit/httpd.git/tree/   Although these 
are for Fedora, not RHEL7, the two are very similar.  If you want 
something specific to RHEL7, download and look at the SRPM for httpd 
provided by Red Hat.

It is uncommented by default because is is used by default on RHEL7 systems.

My opinion is that commenting it out would be a bad thing to do:

- You would probably have to change your systemd unit files under RHEL7 
to start up httpd differently.
- You would make your system non-standard (for a RHEL7 system), making 
things harder for people who are familiar with RHEL7 who administer it 
later.
- mod_systemd is not likely using any significant amount of RAM.

Sounds like a choice of Redhats.  The memory hit is probably trivial though.
