newer versions of systemd support shell like quoting in EnvironmentFile,
204-14 does it. i just checked with ssh service file


 and seems have no control statements like if or

Agreed

i think we could

1) add a postinst script to parse, and modify, /etc/default/openstack
and /etc/default/nova.
logging options will end in $DAEMON_ARGS which we could consume from
service and init.d files

2) launch the service from a shell wrapper :(


both approaches will suit me, i need them because
https://github.com/saltstack/salt/issues/11900

i do prefer the postinst path
