Some kernel upgrades not properly detected

Bug Description

During the master process when searching for kernel upgrades some kernels are not properly detected if they have more than 3 hyphenated parts in their name. For example, I was trying to customize Ubuntu 10.04.2 to use the PAE enabled kernel to access the 4GB of RAM in my machine. My vmlinuz was called vmlinuz-2.6.32-30-generic-pae. The script properly detected that 2.6.32-30 was an upgrade from However, when UCK went looking for the matching initrd.img, it only searched for vmlinuz-2.6.32-30-generic (which I didn't have) and ignored the kernel upgrade. If I remove the last hyphen, the script appears to work fine (i.e. vmlinuz-2.6.32-30-genericpae) In the customize_iso script, function get_latest_kernel the logic reads "$REMASTER_DIR/boot/$1-$2.$3.$4-$5-$6" I believe that $6 needs to be replaced with something like "everything after $5" to handle these potential differences in kernel naming and descriptive tags.

Sorry - I forgot to mention that I was using Ubuntu standard naming conventions for the kernel. I obtained vmlinuz-2.6.32-30-generic-pae by installing the package linux-image-generic-pae I did not customize the file names, so it is likely that other kernels in the Ubuntu repository will exhibit this situation.

Since Ubuntu 12.04 32-bit version sports PAE kernel by default, this bug affects all Ubuntu 12.04 32-bit kernel updates which will not be properly detected in customization process as described above.

@Mart: why do you say "find of fixes"?

Since there appear some /boot/vmlinuz*.efi.signed files in Ubuntu 12.10, kernel update fails again. Kernel is updated, but "uname -a" still reports old kernel on live system. This patch excludes those files and fixes the problem for me.
