And we try very hard not to release things until they pass our QA testing.

We are still finding and correcting issues with the 5.6 things that we
have built (things not properly linking when compared to upstream, etc).

One we release something, we can't take it back.  If we release a
package that is linked incorrectly, it gets out to millions of machines.

If it is broken, it does not matter if it is fast.

Everyone will need to make their own decisions on what they want.

For example, do you want things like this or not:

Verifying certmonger-0.30-4.el5.x86_64.rpm against
certmonger-0.30-4.el5.x86_64.rpm
certmonger-0.30-4.el5.x86_64.rpm FAIL ref:656933 +/-:-10856 %:1

-------------------------

And then looking at the reason for the fails:

What does that mean ... it means that those 2 packages were built
against the wrong version of libtalloc.  Those packages use the older
library for libtalloc, not the newer one.  Will that package work like
the upstream one ... probably not.  I do not make it a practice of
checking Scientific Linux links to upstream.  I only check ones we
specifically have issues with, to see if anyone else gets it to build
correctly.  We initially had this same issue in our 5.6 build and for us
it is now corrected because of our QA process.  It is still in the SL
50x Rolling.

It takes hours to analyze all the packages in a build ... I do not have
hours to spend on doing it for SL ... but here is another error that I
found in the SL tree when figuring out build issues in the CentOS 5.6 tree:

This is not in any way trying to slight the SL distro, it is a very good
product (as is CentOS).  These are just a couple of examples of things
we have fixed in our 5.6 build  in the last week that are also in SL
that I know about because I specifically checked SL when we found the
issue in CentOS.
