Comment # 4 on bug 927223 from Bruno Friedmann

We can add to the review list of how it works :

I mean we have 3 httpd engine prefork mpm and event
Some modules are engine specific like cgi is only for prefork 
event and mpm are looking for mod_cgid 

For example this one is located correctly under /usr/lib64/apache2-event for
event etc which is great.

All share modules are linked to the /usr/lib64/apache2/ directory.
But the script that create /etc/apache2/sysconfig.d/loadmodule.conf

use the wrong location (always /usr/lib64/apache2/*.conf)
it should use the one of the mpm specified in /etc/sysconfig/apache2

otherwise the start_apache script actually failed with
(or ignore the unknown module)

I was able to bypass this crap by symlinking mod_cgid from
/usr/lib64/apache2-event in /usr/lib64/apache2 cause I'm knowing what mpm I'm
using
