Red Hat has historically provided ancient NUT versions with their
distributions (not Fedora though). I guess they decided that it was
better to ship nothing at all.

I have no idea why they did it, but if I had to guess, I'd say that's
because most of their customers don't really care. For three main
reasons:

1. most medium/large datacenters have a small number of large UPSes
with generator backups, so NUT is rather pointless;
2. the datacenter has a big UPS and no generator backup, and people
find their 60 minute runtime enough and don't bother to configure a
large number of machines with NUT, especially since their distribution
of choice would force them to compile from source;
3. they just don't know about the existence of NUT, and continue to
use the suck-ass software from the UPS vendor, which normally eats
half their systems memory with its java-based daemon.

Sorry about the change in the subject, I was goink to ask how hard
would it be to implement some kind of auto-discovery/centralized
configuration for slave upsmon's but after thinking a bit I though it
would be too much work for questionable gain and changed my mind.
