>Description:
	Using the releng netbsd-INSTALL kernel from 2021-07-14 (and even more recent ones)
	sysinst claims

		No root partition defined. Cannot continue.

	after selecting the boot disk wd0 for the upgrade.
	Strangely the system boots just fine from that disk.

fdisk wd0:

BIOS disk geometry:

	Thus sysinst cannot upgrade these systems.
>How-To-Repeat:
	Attempt to upgrade an 8.1_STABLE system with 9.2_STABLE sysinst and above
	partitioning.
>Fix:
	not me this time :-)
