[CentOS-devel] What can SCLo SIG do without authtag

This is more or less a stream of my thoughts, as a respond to the 
yesterdays' CBS hangout [1] which was dedicated to git/cbs issues and 

I've been thinking what the things mentioned on the hangout mean for 
SCLo SIG, especially that the authtag thing (which implies working 
lookaside cache except other stuff if I'm not mistaken) is not ready 
yet, since it needs to be done rather properly than doing it twice 
(which seems correct). Thus, SIG-maintained lookaside cache under rpms/ 
won't work for some time still and we're not able to build already 
released RHSCL content ourselves (in the rpms/ project).

So, what can we do even right now, without authtag working?

Just to sum it up, what are our options right now:
  * git access under sclo/ project works for all SCLo SIG members
  * we can use Fedora's lookaside cache for creating SRPMs, since pretty 
much all the SCL packages are in the Fedora already
  * building RHSCL 1.2 packages from SRPM is not possible, since we'd 
block that NVR for future builds from SCM (we don't want to cause the 
duplicate NVR issue in koji).

Thus, we need to use another disttag --> build into SCL future only as 
described at [2]?

Anyway, if we had the packages ready in sclo/ witch tarballs in fedora 
only -- could someone from CentOS power men do the import into rpms/?

If so, what about bootstraping in this case? Maybe we can come up with 
some cookbook for packages rebuilds, that would be parseable by a tool; 
that tool would create srpm from sclo/ project (specific hash may be 
given so we may build one package twice because to bootstrap) and import 
it and build within rpms/ project..

That should allow us to build RHSCL-1.2 packages without having commit 
rights in rpms/..
