[CentOS] Update to 1503 release problem

[Alessandro Baggi]

 From freedesktop.org:


Q: I want to change a service file, but rpm keeps overwriting it in 
/usr/lib/systemd/system all the time, how should I handle this?

A: The recommended way is to copy the service file from 
/usr/lib/systemd/system to /etc/systemd/system and edit it there. The 
latter directory takes precedence over the former, and rpm will never 
overwrite it. If you want to use the distributed service file again you 
can simply delete (or rename) the service file in /etc/systemd/system again.


This is the way?
