better patch

attached patch might implement this; untested

we do *NOT* use cdboot.img or -boot-info-table but the same method
manifold-boot uses (and MirBSD ISOs use for El Torito boot, incidentally)!

[...]

True.

Adding support for grub2 is trivial as we've the grub.cfg
already in-place available.

What's missing is providing the resulting torito.img out of:

  grub-mkimage --format=i386-pc -o core.img biosdisk iso9660
  cat /usr/lib/grub/i386-pc/cdboot.img core.img > torito.img

through the grml-live templates and invoke mkisofs with torito.img
instead of stage*/isoslinux.bin then.

We might want to consider updating the grub.cfg though, as it
doesn't match our isolinux version nowadays, any
ideas/patches/feedback/... welcome.

Hi,

I thought grml-live already uses grub2 to boot CD but found that it
still uses grub-legacy to boot.

I actually prefer grub-legacy, just logging the issue here for todo tracking.

$ cat grml_cd/boot/grub/menu.lst
