Can't open /boot | biosboot via GPT on raidframe on GPT (NetBSD 9.0/amd64_RC2)



Hello everybody

I'm currently in doubt about everything and need advice from someone who is familiar with NetBSD's boot processes.

I am trying to set up a system with two hard drives as RAID 1. To do this, I create a GPT on both disks with a single partition of the type raid on each. I then mirror these partitions together into a RAID 1 using raidframe. I then create an embedded GPT with the netbsd partitions into the raidframe. the first partition carries the root filesystem from which I also want to boot. And this is what I don't succeed.

The crazy thing is, a while ago I managed a similar setup on the same computer (but with different hard drives). At that time I wrote an installer script and it doesn't seem to work anymore either. I now doubt whether I still made some manual adjustments to make it work.

So if someone has experience with the boot process, I would be very grateful if they could take a look at the script to see if it was correct at the critical points. I am thinking primarily of the places where installboot and gpt biosboot are called.

The error pattern looks like this: when the installation is complete, i get the text of the primary bootstap when booting from hard disk:

	NetBSD/x86 ffsv2 Primary Bootstrap
	Boot failed (errno  2): Can't open /boot

I attach the script directly to this email and remain with
kind regards

Matthias
