You're missing kFreeBSD and Hurd support here, FWIW.

However, I don't think this should require changing grub2 at all.
Nowadays we support other packages dropping files into
/etc/default/grub.d/*.cfg, which are read after /etc/default/grub and
can modify the various variables that are exported by grub-mkconfig to
/etc/grub.d/ scripts.  Could you investigate taking this approach in
init-select instead?  In this case, I think that would be better than
adding another entry to grub2's already large and unwieldy patch stack.

Thanks,
