That's interesting, as for ppc64/ppc64le for AltArch SIG, you're the one
responsible KB for those arches (from what I see on
https://wiki.centos.org/SpecialInterestGroup/AltArch)
So I guess that yes, Sandro tried to reach out and contact you for that
question :-)

When it was discussed at the CBS meeting, (but lot of involved people
weren't there, it was clearly shown that we lack a process for Extras,
and ensuring then than all Alt Arches are following the authoritative
x86_64 distro.
That was becoming a problem too as in fact, nothing from Extras is built
on cbs, but rather on different builders and different processes (so
more or less like @core distro)

The issue that people were seeing was that they wanted to have Extras
enabled within CBS, but due to lack of consistency in Extras, some
builds could fail just because one package is missing from Extras for an
arch, while being available for x86_64.

Does that summarize the issue SIGs members reported in #centos-devel but
also earlier on this list ?
