[cle-release-team] An interesting (bug?) : release problem

[Matthew Jones]

I agree, it kind of feels like at this point that master should be the
parent for kernel, all of those dependencies defined in kernel that were
imported in SAK-18921 moved into master, rather than the other way around.

All master does is define properties and dependencyManagement. I believe if
that was worked around so that we just made kernel a "regular indie" and it
was

oss-parent<-master<-all indies (including kernel)
oss-parent<-master<-base<-all regular stuff

I was kind of hoping at one time for some type of "indie-base" that maven
could use to help figure out the release order so it didn't have to be
manually defined. I'm not sure if this was possible or not.

Perhaps this is the missing piece at the top?

I suppose this wasn't done because I believe there was some idea that
kernels might release faster than the regular cycle of Sakai and master
would get out of sync. And what version would you release master as? This
hasn't happened and 2.9 Sakai has always matched with 1.3.kernel.
Potentially a new master for each indie release of anything, but they've
been locked together since I've been doing it.

Would we ever have a 2 *released* Sakai 2.9's, one with a 1.3 kernel and
one with a 1.4 kernel? That really doesn't feel likely at all anymore. I
think even if we did we'd still have the confusion in the present state.
