Comment # 1 on bug 1023616 from Petr Gajdos

Hi Patrick,

thanks for the report. Unfortunately I do not see any other option besides
dropping APACHE_CONF_INCLUDE_DIRS entirely, but ideas are welcome.

Yes, sysconfig.d files are not included in httpd.conf. Or rather, we do not
count on the fact, that user will include it in httpd.conf. The problem is more
bold as we do support instances:

/usr/share/doc/packages/apache2/README-instances.txt

Remember you can even specify APACHE_HTTPD_CONF in /etc/sysconfig/apache2
another one than /etc/apache2/httpd.conf, so you can get easily to conflict
just by filling wrong sysconfig values.

Not sure how to solve this.
