From a5f020dda1a93657eae1b297a67d054269a3ef0c Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Mon, 7 May 2007 07:53:32 -0400 Subject: [PATCH] update manpages for showmount and mountd This patch updates the manpages for showmount and mountd. It adds a description of the new mountd -r option, and a caveat about the unreliability of showmount -a.
