2024-01-27examples/chroottar.py: allow opening non-zstd tarsHelmut Grohne
When decompression fails, we should raise a tarfile.ReadError rather than a zstandard.ZstdError. Otherwise, tarfile gives up guessing.
2024-01-26improve examples/chroottar.pyHelmut Grohne
* Drop supplementary groups. Very likely, those are not mapped inside and they cannot cause much good. * Sane permission for the root directory. Otherwise no non-root user can access any files.

2024-01-25examples/chroottar.py: work when TMPDIR is privateHelmut Grohne
When TMPDIR has restrictive permissions, the namespace may be unable to access the leading components. Thus we put the supervisor process handling the cleanup into a different namespace that has all the ids plus the current uid mapped. It'll then be able to perform the cleanup (and the initial chown).
