Regarding netsvc.conf, I'm in two minds.
If one is going to use DNS, then surely it makes sense to _use_ it and use
"bind,local". Otherwise, if you omit to make a change in /etc/hosts as well
as DNS you could go badly awry.
If I really can cut /etc/hosts down to the bone that's not very likely to be
a problem, but we'll still have six distinct SP2s at the moment and over 100
nodes, in a fairly fluid environment. (We're doing a lot of consolidation at
the moment, so we keep moving things around and setting up temporary staging
systems etc.)

Thats pretty much the way I have done it with my SP customers. I keep a
minimal /etc/hosts file which contains just AIX servers, and use DNS for
stuff like NT and file/print servers. Besides removing your adminstrative
overhead of maintaining the hosts file, another advantage I see is that you
probably have a secondary DNS server out there in your network and therefore
have some redundancy - which is never a bad thing :)
Oh, and I'm sure you know this Simon but just in case, dont forget to set up
you /etc/netsvc.conf file to use local before bind, or use NSORDER variable.

What I would like to do is just have all of the AIX IP addresses in
/etc/hosts - which would include some HACMP stuff - but ditch all the NT
print servers, AS/400s etc.
