Trying out openSUSE Tumbleweed

"It uses systemd, of course, though it would appear that the integration of systemd has a way to go yet; one quickly encounters services have not yet been set up with proper unit files yet."

Please point exactly what packages are you talking about.. I will personally go and fix them accordingly if time permits.

"Apache has a complicated set of configuration files, but many of the important behavioral details are actually controlled by shell-script assignments in a file under /etc/sysconfig"

Guilty as charged.. however the use of this sysconfig files and -in particular- manual editing of them is neither required nor adviced. (use a2enxxxm a2disxx tools instead)..I agree this stuff needs to be simplified though.
