Package: xen-hypervisor-4.8-amd64
Version: 4.8.5+shim4.10.2+xsa282-1+deb9u11

The 4.8 version of the Xen package has
'GRUB_DEFAULT="Debian GNU/Linux, with Xen hypervisor"' at the bottom of
/etc/default/grub.d/xen.cfg. Unfortunately this fails since Devuan is a
distinct distribution and the match fails.

I think the older solution recommended for Wheezy and Squeeze
(https://wiki.debian.org/Xen#Prioritize_booting_Xen_over_native_Linux) of
adding a symbolic link to /etc/grub.d functions better as it doesn't rely
on an exact string match. That would require coordination with Debian to
rework handling of /etc/grub.d (make a 10_default script which is
meant to be overridden by packages and rename 10_linux to 11_linux).

Somewhere during the work between 4.8 and 4.11, this bug was fixed.
Originally the file attempting to control the behavior was in
xen-hypervisor-<version>-<arch>, but the 4.11 packages moved it to
xen-hypervisor-common (/etc/default/grub.d/xen.cfg).

I'm guessing this also caused problems for Ubuntu and pretty well all
other Debian derivatives. I still find I prefer using dpkg-divert to
rearrange /etc/grub.d more suited to me.

This issue though is without any doubt, fixed.
