Migrate primary disk (duplicate)

[Alexandre D.]

I tried:

1) boot0cfg -Bv -s 1 -t 20 ad2
	=> the boot process stops displaying "F1 FreeBSD ... Default: F1"
2) boot0cfg -Bv -o packet,noupdate -s 1 -t 20 ad2
after doing a sysctl kern.geom.debugflags=16
	=> the boot process passes "F1 FreeBSD ... Default: F1" and then stops at
"can't load kernel" (boot2 I guess)

But your "fdisk -B -b /boot/boot0" should have done that.  I'm not
sure if it has defaults that would work for you though.  boot0cfg
tells you what defaults it will use and lets you change them.

Does "any" include "boot0cfg"?

Depends upon what you want.  Read boot0cfg manpage; it's short.
I used this once:

  boot0cfg -Bv -o packet,noupdate -s 3 -t 9999 ad0
