Public bug reported:
Binary package hint: grub2
I had Kubuntu 9.04 Jaunty installed and fully updated since Alpha4, in
February. jaunty is on sda1 and it uses grub. Over the course of the
updates the kernel was updated nine times, resulting in nine kernel
options listed in /boot/grub/menu.lst. The latest kernel is 26.6.30.
I peeled 40 GB off my HD and installed Kubuntu 9.10 Karmic Alpha4, to
test it. Karmic is on sda5 and it uses grub2.
Along with two Karmic kernel options, all nine of my Jaunty kernel options are
listed in /boot/grub/grub.cfg on sda5. When I boot my notebook I can choose
either Karmic kernel option without problems. When I choose the first option I
get the 2.6.28-10 kernel. When I choose the last option I get the 2.6.28-15.
When I choose any kernel in between the first and the last option I get the
2.6.28-15 kernel. Also, the kernel version is not listed in the grub2 menu
option so it is impossible to tell which kernel option you are choosing unless
you read grub.cfg and ASSUME that the menu lists the kernels in the same
sequence they are listed in grub.cfg
Unlike menu.lst, one cannot manually edit grub.cfg
Here is my sda5 /boot/grub/grub.cfg:
