# We bypass flake-compat's rootSrc cleaning by evading its detection of this as a git
# repo.
# This is done for 3 reasons:
# * To workaround https://github.com/edolstra/flake-compat/issues/25
# * Make `updateMaterilized` scripts work (if filtering is done by `flake-compat`
# the `updateMaterilized` scripts will try to update the copy in the store).
# * Allow more granular filtering done by the tests (the use of `cleanGit` and `cleanSourceWith`
# in `test/default.nix`). If `flake-compat` copies the whole git repo, any change to the
# repo causes a change of input for all tests.
