You just create an configuration snipped that replaces the ExecStart 
line for the daemon in the unit file with startup options for the daemon 
which contains the options you want to change or copy/edit the full unit 
and replace it.

In his sample case above where he's using ExecStart=/usr/sbin/httpd 
$OPTIONS -D FOREGROUND and the environment file /etc/sysconfig/httpd
you would create an configuration snippet which contains 
"ExecStart=/usr/sbin/httpd -D testserver -D FOREGROUND" instead .

The only reason I can think of why distributions decided to split 
configuration out of the legacy sys v initscripts to begin ( you used to 
just tweak it there ) is because the legacy sysv initscript had become 
such a mess that administrator ended up breaking them when they did but 
perhaps someone else posses the historic knowledge why distributions 
started doing that.
