These seems to me to be the first message in the series and provides a
really good summary of the changes at Red Hat which seem to be making
life a lot more difficult for CentOS.
Just figured I'd pull it out of that thread and change the subject line.
Below Johnny's email I've copied another from the original thread,
written by Lamar Owen, which gives some good explanation on how Red
Hat is able to get away with this.
Basically from what I gather, while Red Hat cannot restrict access to
sources, they can restrict access to binaries. And since CentOS has a
goal of binary compatibility with upstream, they are essentially left
trying to hit an unknown target. But (now I'm stretching my limited
knowledge even further) Scientific does not have this restriction
since they are less concerned about exact binary compat.

The RHN AUP simply says that if you redistribute information from RHN
you lose access to RHN. It does not restrict your right to
redistribute anything; it restricts access to future information
distributions from RHN. I know that's splitting hairs, but it does
seem to meet the letter of the license. After all, RHN access is not
required except for updates; if I really wanted to do so I could
redistribute everything I have from RHN at this point in time and
upstream has no legal recourse against that distribution that I know
of (but I am neither a lawyer nor a paralegal; Russ on the other hand
knows of what he speaks....).
They can, however, choose to not distribute anything else to me in the
future, and nothing in the GPL or any other license used by upstream
forces them to distribute anything new to me. And that's the gestalt
of the RHN AUP; it states under what conditions RHN will distribute
the compiled binary code (treated specially by GPL and not as a
derived work) to you, its customer. Once you have received the binary
of a particular version you have the right, under GPL and only for
GPL-covered packages, to receive the source code for that particular
version of that package.
Upstream is very gracious (in my opinion, at least) and distributes
all of its source, not just GPL source and not just to customers but
to the public at large (I say all; I haven't personally verified that
all source in any given RHN channel is indeed available publicly on
ftp.redhat.com, primarily because I don't have access to all
channels). They could distribute only the source that they legally
have to under those licenses that require it, but not for the source
covered under other licenses that do not require redistribution of
source plus modifications.
But just because I have version 1.2.3 of a package does not give me a
guaranteed right under GPL to get 1.2.4 from them. And just because I
can get the source to the 1.2.4 package they distribute does not give
me an automatic right to the corresponding binary as the GPL does
treat the compiled code specially. If you get the binary, you have
the right to the source; if you have the source it is assumed you can
generate the binary yourself (as is proven by the various EL
rebuilds).
The level of difficulty required to generate the binary is not
specified or even addressed by the GPL, nor does the GPL guarantee
your ability to generate the exact same binary as someone else
distributes..... nor is the distributor of the binary restricted at
all in how difficult generating their exact binary, or a 100%
compatible binary, can be. This seems to be the current holdup with
C6.1, in my opinion; you can build *a* binary but will it work just
like *the* binary? Upstream can make it even more difficult than they
already have (and I know it's currently very frustrating to the CentOS
team just from reading this thread!).
Russ, is that summary even close to accurate in your opinion?
These are the facts of life for an EL rebuild distribution user. If
you want a primary access distribution (rather than a secondary
rebuild) you need to find one that meets your needs, either by paying
up for upstream or by going to something else (and there are really
only two suitable enterprise choices for 'something else' in this case
(and in my opinion): OpenSuSE or Debian Stable).
I'm evaluating Debian Stable on IA64 myself, as Debian Stable is the
only actively maintained enterprise-grade distribution (again, in my
opinion) freely available for IA64 (yes, upstream's EL5 is still
available and is still maintained, but it costs six arms and eight
legs to purchase for the machines I have; SLES likewise).
And I don't really currently have the time to rebuild C6 for IA64
myself. I'd love to, and I've had conversations with like-minded
people, and I don't really want to go to Debian on it since I really
want the IA64 boxes to work like all the other servers here which are
running upstream EL rebuilds. But I have more important and necessary
things to do with my time at the moment than to get into the game of
maintaining a private rebuild for IA64 (I say private; even if I had
time to maintain the build I don't have time to deal with the 'issues'
of a public build!).
