Chapter 9294
As a special case, an unregistered depot may be used for local
installation (i.e., the depot and destination root exist on the same
system) if the initiator is the local superuser or has permission to
register the depot (insert permission on the host).
The administrator of a host system must ensure the integrity of new
depots before registering them and ensure that only trustworthy users
are granted permission to insert on the host.
NOTE In addition to registering users, caution should be exercised when
installing or copying from unregistered depots.
