3) not sure if "compile" is right name the layer of packages (go, python, rpm, and bash), does bash really belong here, I don't think we depend on it for the build, do we ? Is there a specific modification to bash that build specific?

Virtually everything depends on bash directly or indirectly through other build tools.

But why can't we use the system provided bash rather then needing the patched version, what specific patches are needed?  I don't then the extra logging is the requirement here.

I agreed our current patch should not alter how anything builds in any direct way.  However it does cause royal havoc on the build order.  It's presence as a buildable object creates many dependency loops.  Not only do a lot of packages depend on bash, bash alos depends on a lot of packages.  Build-pkgs can't determine a build order and must guess.  It wastes a lot of time trying to build packages in the wrong order, and failing, before it stumbles onto a good order.
