This is the right thing to do, applied!
I’m committing a followup that does the same for ‘emacs-minimal’ (even
though ‘emacs-minimal’ has 784 dependent packages, I’m committing to
‘master’ because most of these build in a few seconds.)
I’ve run:
guix challenge emacs \
--substitute-urls='https://mirror.hydra.gnu.org https://berlin.guix.gnu.org'
on a commit before this patch, and there’s the ‘.emacs-real’ binary
alongside a dozen of .elc files that differ. So this may not be the end
of the road, but we should keep monitoring with ‘challenge’ and ‘--check’.
Thank you!
Ludo’.
