My Nixpkgs derivation for Buildstream has been failing recently with the test test_out_of_basedir_hardlinks on Python 3.13.x.
We disabled the test for now, but would like to get this fixed in 2.5.1, as test coverage is now reduced on Nixpkgs.
I've attached a log from the Nix build environment, but it's not clear what the issue is.
Nixpkgs does not have Buildstream 2.5.0 currently, due to protobuf dependencies - we suspect #2022 will land a fix.
