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",
...
}: {
disko.devices = {
disk.main = {
inherit device;
type = "disk";
content = {
type = "gpt";
partitions = {
boot = {
name = "boot";
size = "1M";
type = "EF02"; # for grub MBR
};
esp = {
name = "ESP";
size = "500M";
type = "EF00";
content = {
type = "filesystem";
format = "vfat";
mountpoint = "/boot";
};
};
swap = {
size = "4G";
content = {
type = "swap";
resumeDevice = true;
};
};
root = {
name = "root";
size = "100%";
content = {
type = "lvm_pv";
vg = "root_vg";
};
};
};
};
};
lvm_vg = {
root_vg = {
type = "lvm_vg";
lvs = {
root = {
size = "100%FREE";
content = {
type = "btrfs";
extraArgs = ["-f"];

          subvolumes = {
            "/root" = {
              mountpoint = "/";
            };

            "/persist" = {
              mountOptions = ["subvol=persist" "noatime"];
              mountpoint = "/persist";
            };

            "/nix" = {
              mountOptions = ["subvol=nix" "noatime"];
              mountpoint = "/nix";
            };
          };
        };
      };
    };
  };
};

};

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
