I tried to run tests on current main and following tests fail for me:

The issue seems to be related to tmpdir life cycle, because all of those tests pass if I run them individually. I tried to strace what happens there and the pytest-22 directory is renamed

rename("/var/tmp/portage/dev-python/scikit-build-9999/temp/pytest-of-portage/pytest-22", "/var/tmp/portage/dev-python/scikit-build-9999/temp/pytest-of-portage/pytest-garbage-9e24e15f-96fd-4336-8f55-48394aae858e") = 0

between tests/test_command_line.py::test_no_command and tests/test_command_line.py::test_invalid_command tests.

The issue is related to Gentoo bug https://bugs.gentoo.org/933655

This is because we're passing -o tmp_path_retention_count=0 to save space. Forcing =1 instead resolves it. That said, it would be nice if scikit-build didn't rely on implicit temporary directory persistence.
