Bug#603832: grub-common: Xen hypervisor not default after installation
Package: grub-common
Version: 1.99-21
Followup-For: Bug #603832
I've just been looking at this again. I think the best overall solution would
be to move 20_linux_xen to a priority before 10_linux (e.g. 08_linux_xen). If
someone has gone to the effort of installing Xen then it is very likely that
the want to boot it. Simply modifying GRUB_DEFAULT is unsatisfactory since any
new kernel which is installed will buimp the Xen entries up and require
modification.
If changing the priority of the Xen scriptlet is not acceptable then perhaps it
could be made easier for folks to locally change the priority in a way which is
visible to the package manager and conffile handling? I've enhanced my previous
patch somewhat, with this it is sufficient to:
ln -s /etc/grub.d/20_linux_xen /etc/grub.d/08_linux_xen
add GRUB_PRIORITY_XEN=08 to /etc/default/grub.
Another option might be to make all files under /etc/grub.d symlinks to some
other location (still under /etc for conffile tracking) in order to allow
admins to tweak the priority ordering by renaming the symlinks while still
leaving the actual scriptlets visible to the package manager.
Either way I think it is important to fix this issue for Wheezy.
Cheers,
Ian.
The patch, I couldn't figure out the Makefile.util.def stuff sufficiently well
to add the 08_linux_xen symlink by default...

I think the best overall solution would be to move 20_linux_xen to a priority before 10_linux (e.g. 08_linux_xen). Immediately after hitting send on the previous mail it occurred to me that dpkg-divert might offer the ideal interface for local admins to tweak the priority ordering from the defaults. And indeed: # dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen Does exactly what is required and: # dpkg-divert --rename --remove /etc/grub.d/20_linux_xen and undoes things (on Squeeze and Wheezy). For some reason I had it in my head that dpkg-divert didn't work for conffiles, but on reflection I can't see any reason why that should be the case. In the absence of a change or default ordering this seems like by far the preferable solution, I shall probably update http://wiki.debian.org/Xen to reflect this fairly soon. This info would make a nice addition to README.Debian but otherwise I reckon this bug can be closed.

Bug#603832: grub-common: Xen hypervisor not default after installation
Package: grub-common Version: 1.98+20100804-8 Severity: normal Hello, I have just done a fresh install using the Squeeze Beta1 release. After the installation was completed I installed: xen-hypervisor-4.0-amd64, linux-image-2.6-xen-amd64. Upon rebooting I ended up with the image vmlinuz-2.6.32-5-xen-amd64 booting rather than xen-4.0-amd64.gz with the Linux kernel as a module. For me to boot a working Xen system, I have to manually choose the Xen image from the grub menu, which is okay for a test machine, but not so good for a remote machine. It looks like I can set GRUB_DEFAULT in /etc/default/grub, but it would be nice if Xen was choosen automatically like in Lenny. Also it appears to me that by using the GRUB_DEFAULT option it will not use the most up to date version after a kernel security update.
