It creates hard links from a src/... to a gen/... directory. Some actions do `git reset --hard` in src/. This updates the modification time because of the hard links - even when there are no changes. That in turn leads to unnecessary rebuilds. I have little control over the creation of the hard links. Ævar, everything you wrote is very interesting and helpful. Thank you!
