! It might appear that we could recommend putting sysctl settings into
! /etc/sysctl.conf so that they aren't destroyed by OS version updates.
! This does not work as of OS X 10.4.2, however, because /etc/rc
! promptly overrides whatever SHM settings are read from sysctl.conf :-(
! Perhaps someday we can recommend this ...

!        <para>
!         In OS X 10.3.9 and later, the file <filename>/etc/sysctl.conf</>
!         allows shared memory setting to be saved across operating system
!         upgrades, and is the recommended method for setting these
!         parameters. When using this file, all five shared memory values
!         must be set or the changes will be ignored.
