There's nothing you need to do to enable System V IPC, but on boot
up "ipcs" always says:
IPC status from <running system> as of <date>
Message Queue facility not in system.
Shared Memory facility not in system.
Semaphore facility not in system.
This just means that no one has yet used the Message Queue/Shared Memory
or Semaphore facility yet. They'll be loaded on first use.
If you really want to have them loaded at boot time, add the
following to /etc/system:
In Solaris 7, ipcs will report the unloaded facilities as inactive rather
than "not present in system".
