As long as it's not breaking stuff that works (ie. support for 
non-latestandgreatestlinuxthingie) I don't see any problems.

However, if generic NUT stuff starts to depend on HAL and whatever I'd 
say that we've kissed portability goodbye. Ie, I want to be able to 
speak to SNMP/serial port-equipped upsen using an AIX box in the 
future too.

The above suggestion sounds like a typical "let's solve this the 
non-portable way because my linux-thingie looks nice". People have 
complained a lot about vendors locking applications in hard-to-port 
API:s (Windows for example), this seems to be exactly the same thing.

If NUT wants to prove itself as THE ups monitoring solution we'll have 
to look beyond the desktop. Ie, don't break the good current design. 
Add helpers for desktop-thingies if needed.


/Nikke - who believes in portable code, not stuff locked into a
          specific environment a la Windows.
