Hi,

In Yocto, we have the WIC plugin for building EFI-aware GRUB image.
We also have the bootimg-pcbios: http://git.yoctoproject.org/cgit.cgi/poky/tree/scripts/lib/wic/plugins/source/bootimg-pcbios.py?id=38125456ffa6112941a3608fcba9ed2032353740
which uses Syslinux.

We do not have, however (as far as I know) the plugin for creating legacy BIOS disk image with GRUB instead of the Syslinux. We would like to implement such plugin. If we do already have a way to create disk image with legacy GRUB using WIC, please let me know.

Some of our early work is available here: https://github.com/3mdeb/meta-pcengines/pull/13/files

But we would like to ask which approach should be used in order to avoid rewriting later
when upstreaming the plugin back to the oe-core.

Should we just take (copy) the bootimg-pcbios and modify it for GRUB, or rather extend the bootimg-pcbios somehow to allow for bootloader selection? Any ideas are appreciated.
