Relying on the entry ordering and being able to reference by number is a
bit fragile with the more complex menu structure used these days.

https://wiki.debian.org/Xen#Prioritise_Booting_Xen_Over_Native
recommends:
        dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen
        
TBH I think the correct answer is to upstream a patch to grub renaming
20_linux_xen to 08_linux_xen (or before 10_linux in any case), on the
principal that if you bother to install Xen then you most likely want to
boot it by default. I just never got round to it.
