19 # * To workaround https://github.com/edolstra/flake-compat/issues/25
20 # * Make `updateMaterilized` scripts work (if filtering is done by `flake-compat`
21 # the `updateMaterilized` scripts will try to update the copy in the store).
22 # * Allow more granular filtering done by the tests (the use of `cleanGit` and `cleanSourceWith`
23 # in `test/default.nix`). If `flake-compat` copies the whole git repo, any change to the
24 # repo causes a change of input for all tests.
