you missunderstood me

the problem was "limuts.conf" ignored fro mysqld and solved by the
init-shellscript using ulimit - so with systemd a problem comes back

bad - in my opinion "limts.conf" would be the right place from
the user-side becasue it affects users/groups and finally services
are running as a user/group - so sould be there not exist one
central point of configuration?
