# Attempt to run in the container with the same UID/GID as we have on the host,
# as this results in the correct permissions on files created in the shared
# volumes. This isn't always possible, however, as IDs less than 100 are
# reserved by Debian, and IDs in the low 100s are dynamically assigned to
# various system users and groups. To be safe, if we see a UID/GID less than
# 500, promote it to 501. This is notably necessary on macOS Lion and later,
# where administrator accounts are created with a GID of 20. This solution is
# not foolproof, but it works well in practice.
