Bug#498242: PAE/non-PAE kernel-hypervisor-pairings in menu.lst

[nutzteil at web.de]

Package: grub
Version: 0.97-47
Severity: minor
Files: /usr/sbin/update-grub

debian testing lenny

Hello,

/var/lib/linux-image-2.6.26-1-xen-686/xen-versions is empty, so 'update-grub' gets the entrys for
xen-3.0.3-1-i386-pae.gz
xen-3.0.3-1-i386.gz
xen-3.2-1-i386-nonpae.gz
xen-3.2-1-i386.gz

To get off just the non-PAE-hypervisors:

Okay, hypervisors features can't be tested this way, but all that would go obsolet, if /var/lib/linux-image-2.6.26-1-xen-686/xen-versions has correct entrys again.
Therefor i think of something like CompareVersions() for hypervisor<->/var/lib/linux-image*/xen-versions?


thanks
