loadup.el:185

What failed? If you have a clean tree, and run 'admin/update_autogen -L'
it will regenerate ldefs-boot.el

People who know, know, and people who donʼt know won't know where to
look (and then thereʼs me, who forgets, and has to go re-read
loadup.el 😊). CONTRIBUTE is better than not documenting it (although
maybe it should go in 'admin/release-process' as well).
