Yeah, as none of the other services will really depend on mysql (or note
that you actively use at least) and thus systemd has probably been
diligently trying hard to start it for a while. It will eventually give
up and your systemd-analyze plot will show a nice loooooooooong bar for
this particular service :)

Nope. The brige is the other way around. i.e. systemctl disable will
forward TO chkconfig if there is no native systemd unit, but chkconfig
will NOT forward to systemctl if there is a native systemd unit.

Rule: Always use systemctl, forget chkconfig.

Ahh if you have a US layout then that's likely not an issue you'd get
tripped up by.

Yup, I appreciate I'm holding things up here :s I'll try and get this
done ASAP.
