I'm not sure I follow. What's wrong with supporting env vars like
EPATCH_PATH or EPATCH_DIRS, with whatever 'sane default' that the PM
in question deems proper? Configuration would be simple and unify any
manager that adheres to the spec. If it's implementation-defined, then
each package manager would look in a possibly different directory. If
we're outlining a spec, imo it would be best to at least establish a
common directory so PM authors can rely on it confidently and help
avoid user issues.

If I'm missing some detail that doesn't make my idea any good, please
tell me. It doesn't seem like trouble from where I'm looking.
