Despite the different context I want just to jump in because
some question are not clearly here as we start to migrate our
services to C7 now.
The above mentioned set of source code respectively pkgs are clearly
available for RHEL-6, RHEL-5 and older via upstreams ftp service (as
provided by RH itself). Git.centos.org was communicated as the canonical
upstream for the sources of C7 (not RHEL-7).
Is RH importing the pkgs into the git repository directly?
RHEL-7 vs C7: Are the sources equal or the same?
Are other rebuilders consuming the RHEL-7 sources only via git.centos.org?
Hope that this aren't to many questions at the same time - thanks,
