Exactly, that would be the correct way.
However alternative solutions could be used, like:
ExecStart=/bin/sh -c "$PREF_DM $OPTS"
Uglier, but there is no point in saying it is not capable of.
Moreover, this is free software and people are taking care of their
problems. Kay and Lennart focus on their stuff, we should help to fit
our needs... or wait a possibly endless loop: while
(!dreams_come_true()) complain(); :-)
For instance, I already submitted a way to disable sysv and later
today will send one to disable IPv6.
