Any problem in computer science can be solved with another layer of indirection
they said. So:
Maybe we can just distribute some good defaults (or your internal distribution
for git can ship adapted versions of the default). And instead of just running
a hook, maybe the clone/fetch could tell the client to enable these
predefined hooks.
so maybe we'd need a fetch capability "recommended-hooks" which could look like
recommended-hooks=<name>,<sha1>
The name would indicate what hook you're interested in such as
.git/hooks/pre-commit-warn-huge-size.sample and the sha1 would be the
sha1 of that default hook to ensure nobody has tampered with that script.
I am not sure if we need the sha1, maybe that's overengineered. I mean trusting
a default script is as much as trusting the git binary on your system, isn't it?
