I am curious why the uid/gid here is formatted as +NUMBER instead of the
NUMBER itself...
The '+' prefix means that the user is explicitly an UID (numeric) and
must not be translated to an uid from a username (you can have numeric
user name which maps to a different UID).
In the tests we want to bypass the translation to preserve stable
output.
