--- Comment #6 from Jann Horn <jann+kernelbugzilla-XZ1E9jl8jIdeoWH0uzbU5w@public.gmane.org> ---
For a process that wants to drop privileges and enter a new user namespace for
security, it might make sense to first set up the namespace as uid 0, with all
UIDs mapped, and then drop privileges inside the user namespace.
