well if you have enabled the service and a listening socket
it is the definition of RUNNING

why not? if you have it enabled you expect that it is there

this is expected

do you not undertsand the fact that if i ENABLE mysqld i expect
that it is listening and if anything checks if mysql is available
it has to get YES at answer if mysqld is enabled from the begin of
the boot process

nothing is preventing anything because you see a problem where
no problem exists and with your view you make problems on
machines where a lot of services are depending on mysql

i tried to explain this thousands of times and getting tired
of your non-understanding that mysqld has to accept connections
as soon as possible and if oyu do not want mysqld started
so do NOT enable mysqld

they will reject you because you are the only person seeing
a problem and not because there is one
