No problem, I guess my response was a bit over the top as
well.

Yes, as far as I'm aware you are.

That depends a lot on your hardware. Usually -current has
best hardware 
support but things may be broken. In doubt it's the latest
stable 
release.

My main problem is that I don't have nearly as much hardware
to test on 
as I'd need - I'm lucky I have one example of each pre-G5
family. For 
instance I'm sorely lacking:
- - an Old World Mac with /chaos/control graphics hardware -
should work 
but I can't test it
- - a Heathrow-based PowerBook ( Wallstreet, Lombard or 1st
generation 
iBook G3 ) - I know there's trouble with the graphics chips,
media bay 
support has been bitrotting ( only tested on my PB4300c -
works fine 
there though ), some PMU operations are known troublesome (
like 
ejecting PCMCIA cards, brightness control etc. )
- - a 601-based PCI Mac. Support for this CPU is available
in other ports 
so supporting it on macppc should be easy. Can't do it
without hardware 
though.
- - a PowerMac G4 - we lack support for some of the audio
hardware, 
sensors etc.
- - anything G5 based. We have support for the CPU and the
host bridge 
but not much more. I'd really like to add the missing bits
but without 
hardware that's pretty much impossible.

Since 4.0 is supposed to be released soon I'd like you to
keep testing 
it when a new build is available - we can't possibly test on
all 
possible hardware combinations, not even close, so we need
your help 
there.
About -current - it's fairly stable right now as far as I
can tell ( 
all my machines run -current ) but since it's constantly
being worked 
on things can and will break occasionally. I would not
recommend using 
- -current on anything important.

Thanks!

have fun
