I don't know who contact but the site http://without-systemd.org isn't
working (it throws database error):

*Warning*:
include(/usr/share/mediawiki-extensions/base/ExtensionFunctions.php):
failed to open stream: No such file or directory in
*/etc/mediawiki-extensions/extensions.php* on line *4*

in */etc/mediawiki-extensions/extensions.php* on line *4*

A database query error has occurred. This may indicate a bug in the
software.

Can somebody contact the site admin?

Cheers,
