+If
+.B CLONE_NEWIPC
+is set, then create the process in a new IPC namespace.
+If this flag is not set, then (as with
+.BR fork (2)),
+the process is created in the same IPC namespace as
+the calling process.
+This flag is intended for the implementation of control groups.
+
+An IPC namespace consists of the set of identifiers for
+System V IPC objects.
+(These objects are created using
+.BR msgctl (2),
+.BR semctl (2),
+and
+.BR shmctl (2)).
+Objects created in an IPC namespace are visible to other processes
+that are members of that namespace,
+but are not visible to processes in other IPC namespaces.
+
+Use of this flag requires: a kernel configured with the
+.B CONFIG_SYSVIPC
+and
+.B CONFIG_IPC_NS
+configuration options and that the process be privileged
+.RB ( CAP_SYS_ADMIN ).
+This flag can't be specified in conjunction with
+.BR CLONE_SYSVSEM .
