Almost certainly.
Much of the HostRes code is just as O/S-specific as the MIB-II
stuff.  When I proposed adding "host" to the default list a
couple of years ago, this was the main argument against doing so.

Indeed.
Sigh!

The trouble is that if we don't start pushing it onto "broken" systems,
very little will happen.  The HostResources implementation is some
eight years old now, and development has been sporadic at best.
SIGH!

I'm not sure what timescale we're thinking of for 5.3, but it may
well be a little late to push this now.  So you're probably right: for
5.3, just enable it on known good architectures.

But once that's out, we should perhaps consider enabling it by
default on the main development line, and wait for the complaints
(and fixes?) to come flooding in.


The other thing that might help is a move towards greater use of
the Hardware Abstraction Layer that I started to put in place a
couple of months ago.   It currently only covers CPU and memory
(and only for Linux boxes), but it's a step in the right direction.

But again, that's probably more of a 5.4.dev thing.

In terms of snmpd.conf configuration - probably not.
There are a few aspects of the existing directives that might
need to be tweaked slightly, but I'd expect to keep things
backward compatible.
  The most visible changes would probably affect the contents
of the MIB tables that were produced as a result - particularly
with the linkage between the trigger tables and event entries.

Given that most people probably don't manipulate these directly,
then I doubt this would be particularly significant.
