mkpart(1M) man page, there and gone!

[Larry Williamson]

The man page for mkpart(1M) is in the older Unix System V/386 System
Administrators  Reference Manual (for S5R3.0). This is a thin book
published by Prentice Hall. I also have a more up to date book, same
title, but with the subtitle "Release 3.2". This is a much thicker
book that contains man pages for sections 1, 1M, 4, 5 & 7.

But! This newer manual does not have the man page for mkpart(1M).

Is this an oversight, an error?
