The ZERO release is always going to take longer than the others.

The Original CentOS 3 release did not even have a ZERO release.  We
didn't finish it until 3.1 had been out for some time and we released
3.1 as our first release.

That first release happened (for 3.1) on 3.19.2004:

The Red Hat 3.0 release happened on October 23, 2003.

That is 5 months.

The 4.0 release cycle and the 5.0 release cycle was much better because
the Beta and RC releases were much closer in time and content to the
actual released ISOs and we were able to build the first release version
on our beta.

This is NOT the case with 6.0.  First off, we can not use any of the
existing infrastructure to build on because we can not build on a CentOS
4 or CentOS 5 machine because of the changing of MD5SUM in the RPMs

Secondly, the distribution will not build on the Beta (much like the 3.x
release and UNLIKE the 4.0 and 5.0 releases).  Not only that, but
upstream used many "non released" packages to build on ... packages we
can not see or get.

Now, because of those things and because we choose to stop work on 6.0
to build out 5.6 and 4.9, the 6.0 release is late.

We do not need a discussion of how bad CentOS sucks every week on this list.

If you like CentOS, use it ... if you like SL then use that.

This list is for the CentOS distribution .. it is not for how to use SL
or how to migrate to SL.  SL is a great product and if people want to
use it then I am all for it ... however, talk about it on their mailing
list, not ours.
