The remaining semaphore settings are read-only as far as
<command>sysctl</command> is concerned, but can be changed
before boot using the <command>loader</command> prompt:
<screen>
<prompt>(loader)</prompt> <userinput>set kern.ipc.semmni=256</userinput>
<prompt>(loader)</prompt> <userinput>set kern.ipc.semmns=512</userinput>
<prompt>(loader)</prompt> <userinput>set kern.ipc.semmnu=256</userinput>

Similarly these can be saved between reboots in
<filename>/boot/loader.conf</filename>.
<command>sysctl</command> is concerned, but can be set in
<filename>/boot/loader.conf</filename>:
<programlisting>
kern.ipc.semmni=256
kern.ipc.semmns=512
kern.ipc.semmnu=256
</programlisting>
After modifying these values a reboot is required for the new
settings to take affect.
