`make test` fails in containerized build, 'overlay' not supported as root filesystem

[stefan0xC]

I'm running the build in a podman container but similar to #981 the test fails:

python -m unittest  -b test/test_tools.py

I can't reproduce that in a chroot, but the same test fails:

Seems to be a duplicate or neighbour of #1389 which is fixed by 3a56a4c .

Can you confirm this with your podman setup?

I think you're right. It seems to work just fine. Thanks for fixing the issue.
