I'm not asking that a beta "work", production or otherwise. But the entire 
_point_ of a beta is to test in "real world" conditions. Otherwise they may 
as well, just release it and be done.

For example, many people use CD-RWs for back-ups in production servers. Should 
no one have even tried to write a CD because it could lose data or not work? 
They should not _rely_ on those as valid back-ups, but should they just not 
bother testing them? There are a number of people (judging by the bugzilla 
postings) having difficulty with CD recording in the Phoebe beta. If it had 
been released with that percentage of people unable to do a common task, how 
would that reflect on the release?

Same goes for sendmail. If it is never activated as an incoming SMTP MTA, how 
will anyone know if it even works? Should we just assume it will? Phoebe != 
Psyche, so everything should be tested in a "production way" in a "production 
environment", just not for "production purposes". That has at least been my 
experience with "beta" software for the last dozen years.

Since sendmail is installed by default and mail services are one of the most 
common uses for Linux boxen (along with web serving) and many other programs 
rely on sendmail (or other MTA) it would seem counter-productive to say 
"don't actually use it in a real way" for a beta test. Should I also assume 
that I should never let apache get tested by more than 3 people? Or would it 
perhaps be helpful to see if the new kernel threads cause apache to fail 
under load? (apachebench is nowhere near real world testing)

Hmmm, a remote root exploit with example code in the wild that produces a 
remote shell to the user. Nah, that couldn't cause any problems?

So if I build my own, am I still a beta tester? Does it still help RH find out 
if their stuff works? Maybe I should recompile everything or install some 
Mandrake rpms and then complain that stuff is broken in the beta.

It perhaps wouldn't matter quite as much if anything got put in rawhide 
nowadays, but that seems to be dead as well. At least then it could be 
assumed it was built on something similar to Phoebe.
