error with /usr/sbin/grub-mkconfig Read-only file system??
This was strange. I had not seen this before :
run-parts: executing /etc/kernel/postinst.d/zz-update-grub
5.12.12-genunix /boot/vmlinux-5.12.12-genunix
/usr/sbin/grub-mkconfig: 257: cannot create /boot/grub/grub.cfg.new:

Wow. How the heck did that happen?

OKay so the handling of HFS must be borked in some way.

That is my kernel compile running just fine and perhaps I did an
apt-get update and/or upgrade and some hfs handling thing is borked.
So these old PowerMac things need that HFS partition to boot and it
seems something strange has happened ( again ) with the boot process.
Is this a known thing?
