Thanks a lot for pointing that out! That explains part of the problem.
The corresponding source RPMs are indeed identical (I checked :-) ), so
the packages were (indeed) rebuilt. That was not at all obvious to me.
OTOH: I probably would have guessed if there had been a corresponding
e-mail to Centos-Announce. At this point, I would like to add that I am
extremely impressed by the CentOS project and that I do not want to
blame anybody for forgetting such an e-mail (or maybe it was just lost
somewhere in SMTP-land) - I just want to state that fact. Thanks for
putting in all that hard work!
With that new knowledge, I also checked my other issues wrt to the
container-tools package: Same module issue. So there is a pattern. But
there is also the pattern that I cannot find the corresponding
CentOS-Announce e-mail. Strange, isn't it?
This still leaves me wondering if there should be an attempt at
providing a CentOS OVAL file similar to the one by RH that is not
generated by taking the upstream file and running some uninspired
sed-script on it, like (for reference):
??? sed -e 's,/etc/redhat-release,/etc/centos-release,g' -e
's/199e2f91fd431d51/05b555b38483c65d/g'
However, the question could be asked if such an OVAL file would be of
any use, in the light of possibly missing CESA announce e-Mails, because
that advisory information must some be translated into the OCAL XML.
Having said all this: maybe there is some deeper problem here, because
of that pattern of missing announce e-mails that correspond with
packages that differ in the final version number with respect to the
upstream package. Or is this just a coincidence?
