I've found the CUPS config stuff somewhat problematic.
The config file is generated from another config file, and some other
things, that trigger
regenerating the config. Sometimes even the printer ink level is
regenerating cups configs,
which is really annoying. Modifying files in /etc is not a very nice
way to handle that indeed.
The problem is known upstream, and seems to be won't fix. If we could
get around that in any sane way,
I would be very happy.
