Yeah, I scratched my head a bit for the correct boot.cfg when I experimented
with RootFS-on-RAID-over-wedges some time back:

https://www.unitedbsd.com/d/1479-using-some-kind-of-raid0stripe-for-root-filesystem/7

There, only the boot.cfg in EFI:/efi/netbsd/ mattered. The one written by
sysinst(8) inside the RAID root wedge didn't matter. And, of course, here, only
the /boot.cfg in the `Root1' wedge mattered. The others are not read by the
bootloader.

Is there any kind of RAID/CCD/CGD involved in your setup?
