Re: [Dorset] Changing Grub2 Menu under Kubuntu 10.10

2011-03-29 Thread DJ Lonsdale 
Try using synaptic package manager to remove old kernels.

Grub2 then should update when it finds they are gone.

 Looking into  https://help.ubuntu.com/community/Grub2
 
 and picking out the needed bits, here is how to trim down that menu
 list.
 
 1. in /boot, there are three entries for each revision of the kernel. 
 
 
 examples: 
 abi-2.6.32-25-generic 
 initrd.img-2.6.32-25-generic  
 vmcoreinfo-2.6.32-25-generic
 
 abi-2.6.35-22-generic 
 initrd.img-2.6.35-22-generic  
 vmcoreinfo-2.6.35-22-generic
 
 config-2.6.35-24-generic  
 System.map-2.6.35-24-generic  
 vmlinuz-2.6.35-24-generic
 
 Note there are different files for different versions - improvements I
 guess. 
 
 I left the 35-27 and 35-28 versions in. 
 
 2. Move the unwanted versions to somewhere else. 
 
 3. sudo update-grub
 Takes a minute or two
 
 4. reboot to prove it works. It did for me.

Alternatively, I believe you can remove them with your package manager,
which also frees up some space.
