this probably warrants some broader discussion..
I think the only way to implement PGO and reproduciblity is to treat
the profiles as allowed generated input to the build (i.e., lift the
restriction of "all pre-generated parts of the upstream source must be
regenerated as part of the build" for them).
So, how to move forward? This feels a bit like the community behind
reproducible builds should paper out a general solution to deal with PGO
in binary distributions, which is unlikely to happen overnight. Do we
agree on that? If so, I think we should let rust-coreutils migrate now.
Which also means that we should ensure "this probably warrants some
broader discussion". I have the impression that's somewhat already
happening, but I've only seen it on IRC. Can somebody link to broader
discussion (if it exists already)?
