Id love to say it worked but sadly it didn't :(
Indeed,
I searched deeper and found that grub use dpkg --compare-version to find the latest version , if you're not on debian i suppose it's another method
So it clean up the names with :
echo <your-version> |sed -e "s/[^-]*-//;s/[._-]\(pre\|rc\|test\|git\|old\|trunk\)/~/g"
and then compare it with :
dpkg --compare-version <version1> gt <version2>
exemple :
dpkg --compare-versions 2.6.32 gt syms-2.6.32
wich gives syms winner, never mind the numbers
3 possible workaround :
The simplest is to rename your xen hypervisors, by prepending 'xen-' to them : mv xen-4.0.2-rc3-pre.gz xen-xen-4.0.2-rc3-pre.gz
i tested and it works.
The second is to modify the regexp : i didn't even tried ^^
The third is to patch : /usr/lib/grub/grub-mkconfig_lib
add the bold lines to this function :
version_test_gt ()
{
local sedexp="s/[^-]*-//;s/[._-]\(pre\|rc\|test\|git\|old\|trunk\)/~\1/g"
local a=`echo $1 | sed -e "$sedexp"`
local b=`echo $2 | sed -e "$sedexp"`
local cmp=gt
if [ "x$b" = "x" ] ; then
return 0
fi
case $a:$b in
*.old:*.old) ;;
*.old:*) a=`echo -n $a | sed -e s/\.old$//` ; cmp=gt ;;
*:*.old) b=`echo -n $b | sed -e s/\.old$//` ; cmp=ge ;;
syms-*:syms-*) cmp=gt;;
*:syms-*) cmp=lt;;
syms-*:*) cmp=lt;;
esac
dpkg --compare-versions "$a" $cmp "$b"
return $?
}
I tested too, it works fine and it's my prefered.

Edit
the 20_xen_linux script :
change :
xen_list=`for i in /boot/xen*; do
by :
xen_list=`for i in \`ls /boot/xen*\`; do
it should work( maybe( perhaps) )

Hey all,
I have moved 10_Linux to 50_Linux and ran update-grub which is fine.
The problem I have is that there is xen-syms in /boot And that is being put first in the boot list which is incorrect.
How do you make /xen.gz at the top so it is booted first?
Thanks
Ian
What is your OS ?
