Did --dry-run stop working, or is it me? Basically the flag is ignored
on the latest checkout.

It does not quite work in the presence of grafts. As far as I understand
from testing, the ungrafted packages are still built, and then it stops
only before grafting.

Specifically, to determine whether a binary needs to be grafted, Guix
must check whether that binary depends on one of the things that we
would graft.
To do that, it must either have access to substitute information, or
have a local build of the thing at hand.
Thus, when substitutes are lacking, it will tend to build things right
away so that it can answer that question.
I agree this isn’t great, but I’m not sure how to improve on that.
(Nevertheless, it is better than answering the question based on
compile-time dependencies as was done before.)

Grafts, I thought, an intermediate solution to prevent excessive
rebuilds. Still, regularly we would rebuild everything, right? Or are
we now grafting on grafting?

Yes. No. :-) We undo the grafts in core-updates and rebuild everything
there.

Exactly. So far we did not rebuild as frequently as we’d like due to
limited resources, but hopefully the situation will improve when our new
server is up and running!
