>Description:
	The installers put in place a sysctl.conf file that does
	nothing, but which contains a $FreeBSD$ header. This results
	in a no-op file serves only to create noise when mergemaster
	is run on a system that actually uses sysctl.conf to override
	default settings. Since the distribution will never use
	this file to set system defaults, the $FreeBSD$ header is
	pointless.

	As with /etc/rc.local, this file should not be present
	unless explicitly created by the system administrator.
>How-To-Repeat:
	n/a
>Fix:
	Remove /etc/sysctl.conf from the distribution installs.
