slight change in the initscript
this is all very odd;
out of the blue the SFA service within its f20 VM (inside bigjohn that is a f21 LXC host) was not starting properly any longer..
the test to decide whether to start postgresql had to be rewritten, reading now
check || { start-db ; ... }
rather than
if [ ! check ] ; then start-db ... ; fi
