May I kindly ask you to elaborate on that? Please, because I'm interested too. 
Where is better information to be had or can you at least point out where 
exactly one needs to start to iron out the failings of the mentioned document?

I'm not exactly understanding what you mean by "preserves future changes to 
the system file". I always had the impression that my changes to config files can 
either be overwritten by updates (bad), merged into the newer config files 
(difficult without administrator intervention) or left alone and new config files 
installed as "release" files, or the new files installed and the old ones 
backed-up as *.pkg-old.

Preserves seem always to be from the past yield, can the future be preserved?

Also, what do you mean exactly by "system file" in the case of systemd - those 
in /lib/systemd/system/?

Cheers and thank you
