Michael Kerrisk 89070c1a7c 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.

Michael Kerrisk 7f98a23983 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.

SYNOPSIS doesn't contain important information, and may
