attempt: on a BIOS boot only system, I am trying to assign a id or uudi to a disko config because /dev/sdx gets switched around and becomes less viable in a raid setup
problem: switching to or using /dev/disk/by-id/<some-device> causes a GRUB2 error after rebuild: "This GPT partition label contains no BIOS Boot Partition; embedding won't be possible."
extra context: this is on a system that already has a disko config setup and im trying to switch it, i cannot bootstrap with /dev/disk/by-id disk either.

I've been stuck on this for a few days, just a nudge in the right direction even if its pointing out something in the docs, or a workaround would be very helpful.

config:
""

device ? throw "Set this to your disk device, e.g. /dev/sda",
...

disk.main = {
inherit device;

In reply to @wolfeexd:matrix.org
if /dev/disk/by-id/xxx is just a link to /dev/sdx then im not sure what would grub to fail
