user_namespaces.7: Clarify meaning of privilege in a user namespace
...
Having privilege in a user NS only allows privileged
operations on resources governed by that user NS. Many
privileged operations relate to resources that have no
association with any namespace type, and only processes
with privilege in the initial user NS can perform those
operations.

unix.7: Update text on socket permissions on other systems
...
At least some of the modern BSDs seem to check for write
permission on a socket. (I tested OpenBSD 5.9.) On Solaris 10,
some light testing suggested that write permission is still
not checked on that system.
