	I'm updating a machine from:

FreeBSD 12.0-CURRENT #0 r331659: Thu Mar 29 12:31:36 EDT 2018 amd64

	to CURRENT (as of last midnight.
	Does this, in src/UPDATING:

	[8] In order to have a kernel that can run the 4.x binaries
	needed to do an installworld, you must include the
	COMPAT_FREEBSD4 option in your kernel.  Failure to do so may
	leave you with a system that is hard to boot to recover. A
	similar kernel option COMPAT_FREEBSD5 is required to run the 5.x
	binaries on more recent kernels.  And so on for COMPAT_FREEBSD6
	and COMPAT_FREEBSD7.

	 still apply?
	 (It seems ... irrational ... one would need compatibility stuff
 going back to FreeBSD 4 to rebuild/update FreeBSD 13.)


			Respectfully,


				Robert Huff
