Sigh. Add note about the FILE FIASCO.

Also notes about FFS_ROOT and CD9660_ROOT and DEVFS cautions.

It is not a good time to live in -current.

+	The size of FILE was changed.  This breaks upgrading.  If
+	you must upgrade, be prepared for pain.  It also breaks almost
+	all binaries that you've compiled on -current.  You are warned
+	that before upgrading would be a good time to do a level 0
+	dump of your system.  No, really, I mean it this time.
+
+	To get to the new system, you'll need to use the following
+	workaround.  Hopefully this can be sorted out so that we
+	don't have to move this to the updating section.
+
+	To get around the installworld problem, do:
+		# cd /usr/src/usr.bin/sed
+		# make install
+		# cd /usr/src
+		# make installworld
+	If that doesn't work, then try:
+		# make -k installworld
+		# make installworld

+	DEVFS is now the default.  If you use vinum, make sure that you
+	do not include devfs in your kernel as problems result.

+	FFS_ROOT and CD9660_ROOT have been removed or depricated.
+	Remove them from your config.
