if I had a formed proposal I would have made it, instead of asking :)

I found that when I tried, because there are often not completely
obvious tools in play (at least until you get familiar with what
everything will need).


is there some way system config details could be saved and signed in the
same way that build products can be recorded and cached, and if there's
reason to believe the system has not changed, reuse those?  Or does that
risk heading in the direction of "builds may not be repeatable"?
