Mac OS X Server 1.x: Modifying Allocation of Paging & Swapping Space

I want to change how my Mac OS X Server uses space for paging and swapping. I manually edited the file /etc/swaptab, but now mach_swapon fails.
Note: This article pertains to Mac OS X Server versions 1.x, which were released prior to May 2001.

Mac OS X is pre-configured for optimum performance on PowerPC platforms. Therefore, modification of paging and swap space is not recommended. However, if you wish to modify these parameters, use /sbin/mach_swapon to make those changes rather than manually editing the /etc/swaptab file. Note that /sbin/mach_swapon will fail if the file listed in /etc/swaptab does not exist.
