As you can see on its homepage, it doesn't support this syntax yet; would be a nice feature to have, I used to keep backup kernels around in the early days too and now I rename them to have Nouveau and NVIDIA specific boots.
Could you please use '--list-kernels' with the today's -9999 version? I've added additional info about mtime which could help debug this.

Ah does eclean-kernel base age on mtime .. (or really install time) .. So when trying to generate a sample for earlier testing of grub.cfg generation .. I rebuilt/installed an "earlier kernel version" it changed the mtime to be newer and now " the old does not get removed .. as the running kernel is the oldest mtime .. so reinstall of running kernel should fix this ? As an aside .. the kernel "make install" creates the .old suffixes on reinstalls .. for the same versions .. the .olds should be removed preferentially before other versions in my opinion .. but others may differ .. tested: eclean-kernel --list-kernels 3.11.5-gentoo [3.11.5-gentoo]: - vmlinuz: /boot/vmlinuz-3.11.5-gentoo - systemmap: /boot/System.map-3.11.5-gentoo - config: /boot/config-3.11.5-gentoo - modules: /lib64/modules/3.11.5-gentoo - build: /usr/src/linux-3.11.5-gentoo - last modified: 2013-10-18 11:27:17 3.11.4-gentoo [3.11.4-gentoo]: - vmlinuz: /boot/vmlinuz-3.11.4-gentoo - systemmap: /boot/System.map-3.11.4-gentoo - config: /boot/config-3.11.4-gentoo - modules: /lib64/modules/3.11.4-gentoo - build: /usr/src/linux-3.11.4-gentoo - last modified: 2013-10-14 20:51:04 3.11.4-gentoo.old [3.11.4-gentoo]: - vmlinuz: /boot/vmlinuz-3.11.4-gentoo.old - systemmap: /boot/System.map-3.11.4-gentoo.old - config: /boot/config-3.11.4-gentoo.old - modules: /lib64/modules/3.11.4-gentoo - build: /usr/src/linux-3.11.4-gentoo - last modified: 2013-10-14 20:40:13 3.11.5-gentoo.old [3.11.5-gentoo]: - vmlinuz: /boot/vmlinuz-3.11.5-gentoo.old - systemmap: /boot/System.map-3.11.5-gentoo.old - config: /boot/config-3.11.5-gentoo.old - modules: /lib64/modules/3.11.5-gentoo - build: /usr/src/linux-3.11.5-gentoo - last modified: 2013-10-14 17:58:47 eclean-kernel -n 2 --debug * Trying bootloader lilo * Trying bootloader grub2 ** /boot/grub/grub.cfg found * In get_removal_list() ** Config is autogenerated, ignoring * Removing kernel 3.11.4-gentoo.old (not referenced by bootloader (grub2)) - /boot/vmlinuz-3.11.4-gentoo.old - /boot/System.map-3.11.4-gentoo.old - /boot/config-3.11.4-gentoo.old * Removing kernel 3.11.5-gentoo.old (not referenced by bootloader (grub2)) - /boot/vmlinuz-3.11.5-gentoo.old - /boot/System.map-3.11.5-gentoo.old - /boot/config-3.11.5-gentoo.old Removed 2 kernels * Calling grub2-mkconfig Generating grub.cfg ...

Yes, it uses mtime of vmlinuz purely. I didn't really want to implement any kind of version parsing since that would be complex and wouldn't be able to handle all the different cases (like having multiple variants of kernels or installing older version of kernel for some reason).
With testing pre-release of ek2 (1.99.0), it does version comparison now. I think it should fix your issue (and introduce a ton others ;-)).

Created attachment 441166 [details] eclean-kernel-testing.txt compare old and new on a third machine more testing .. failure to list ... is it related to age of the files .. this is on a third live machine .. on my first initial tests (on first live machine) new version did not crash .. but on rebuild of /boot to similar state it did. I added .old files by doing make install modules_install from src directories again .. odd results that it does not work now .. when it did work .. I failed to copy the actual output ... sorry
I guess I need to verify that I didn't break .old handling in late refactor. I'll take a look at it tomorrow.
It actually turned out to be a trivial over-optimization, and I've fixed it in -9999 now. As for the behavior regarding .old, I think the current one makes more sense. It is especially important if you modify the current kernel, rebuild it and then figure out the new version doesn't work. Then you'd rather have the known-working .old than some older version. It also fits 'make install' behavior better -- i.e. vmlinuz.old points at previous kernel, possibly moved to .old.
yeah that seems to work better .. I suspect the boot loader config (i.e. grub2-mkconfig, lilo, etc) is not yet called in the new version ..
(In reply to Derk W te Bokkel from comment #14) > yeah that seems to work better .. I suspect the boot loader config (i.e. > grub2-mkconfig, lilo, etc) is not yet called in the new version .. Yes, I'm still thinking how to solve that best. I'll probably go for not having any specific Bootloader classes like before, and instead create a regular post-removal event for grub2. I suspect all of bootloader support you need is to call grub2-mkconfig (or something like this), correct?
yes normal grub2 command line is: grub2-mkconfig -o /boot/grub/grub.cfg
