The new way to do this is exactly what Gordon suggested - using 
`systemctl edit <servicename>` creates an override in 
`/etc/systemd/system/httpd.service.d/override.conf`.

The only issue is that there is no `systemctl` related command to remove 
this override - you will have to remember to `rm -rf 
/etc/systemd/system/httpd.service.d` if/when you want to remove that 
override.
