--------------------+------------------------------------------------------- We've recently discovered that we need to check whether CUPS is running in
a few places, e.g. when adding printers. The obvious way, using lpstat
-r, is actually nontrivial since that command merely prints output,
instead of returning a status value of success for running and failure for
not-running.
Thus, we end up parsing its output, which is fragile to upstream changing
that output.
It looks like we currently check for CUPS' status in:
{{{
config/cluster-cups-config/debian/postinst
config/cluster-cups-config/debian/configure-athena-printers
}}}
but that's just a quick check of the past 300 transactions in source-
commits.
We should (a) file an upstream bug that lpstat -r should return a usable
status code, and (b) try to make our scripts robust to any changes
upstream might decide to make.
