The user could tell the server operator to rename them or remove them because they are not doing anything useful, but then as long as everybody knows they are not doing anything, it is OK to leave that sleeping dog lie, as they are not doing anything harmful anyway. That brings us one step further back to question if the hints are useful in the first place, though ;-). > 2. Should these hints be suppressed with --quiet?

I do not think having a non-executable file whose name happens to be the same as a hook is an error in the first place [*1*], so I do not think it is unreasonable for --quiet to squelch. side note [*1*]: we need to make sure that it is clearly documented that such a file is not a hook, of course. > 3.

This probably is much deeper issue and templates/hooks--* is merely a tip of iceberg, I suspect. In general build artifacts from different versions of Git in the same build area could interfere the tests in other ways (e.g. a test for "git help" output could try to grab a deprecated command left in bin-wrappers/ from previous build of an ancient version), and could potentially interfere things other than the tests (e.g. the 'install' target of the Makefile may be written loosely to install everything in a directory). In general, I am a bit pessimistic and suspect that the best we could say is "if you want to absolutely avoid such interference, 'make distclean' before switching to test another revision". > 4.
