I wonder if there is a limit (e.g. 128GB) for the boot partition, and if
we happen to put the bootloader after that, but Solaris and OpenBSD put
it earlier.  The easy way to test would be to create (e.g.) a 120GB root
partition.  If that doesn't work, we'll probably need to add some debug
to the boot block:

I wonder if booting with "boot-debug?" set would help?  Is that boot -V?
