I've got a Ubuntu server 10.04 that have been running since 10.04. Today when apticron mailed me about new packages the installation of a new kernel update failed due to a full /boot partition. Looking into it I have 226 MB of files in /boot and about 15 different revision of the kernel.
For each version I have the following 6 files:
vmlinuz-2.6.32-21-generic-pae vmcoreinfo-2.6.32-21-generic-pae System.map-2.6.32-21-generic-pae initrd.img-2.6.32-21-generic-pae config-2.6.32-21-generic-pae abi-2.6.32-21-generic-pae
Is it safe to just delete the oldest? Or is there a "proper" method of disposing old versions.
