From 10f666af84d48e89e4e2960415c9b616fce4077f Mon Sep 17 00:00:00 2001
From: dyson <dyson@FreeBSD.org>

Subject: This is the kernel Lite/2 commit.  There are some requisite userland
 changes, so don't expect to be able to run the kernel as-is (very well)
 without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.
