Just  as small update I installed netBSD 10.0 macppc on qemu-9.0 with
this guide:

https://www.reddit.com/r/BSD/comments/a0re4e/tip_to_install_netbsdmacppc_in_qemusystemppc/

basically it uses  pdisk for making Apple Partition map with small HFS
partition in addition to usual swap/root  slices,
then  from chroot into just installed system makes small iso with just
ofwboot.xcf bootloader and dd it to HFS partition.

Be sure to read answer that says basically that after answering "a"
(using existing disklabel in installer)
you still need to set  newfs  flag manually.

I tried answer "c" initially and  was unable to get rid of wrong
disklabel afterwards, so i started from scratch.

I hoped to find https://man.netbsd.org/intrctl.8 {just for seeing how
kernel assigned interrupts}
but I can't see it in minimal install?
