Your initramfs does not meet the naming convention expected by /etc/grub.d/10_linux. Use something more sane.
ina(In reply to Mike Gilbert from comment #1) > Your initramfs does not meet the naming convention expected by > /etc/grub.d/10_linux. Use something more sane. I am using genkernel all --no-clean --no-mountboot --zfs --bootloader=grub2 --splash --callback="emerge @module-rebuild" --menuconfig --kernname="devel-3.17.7-stage2" to generate kernel, but in /etc/grub.d/10_linux, it use version=`echo $basename | sed -e "s,^[^0-9]*-,,g"` to generate version string. It is my personal fault. But I think the 10_linux should get improved, because this means my kernel name can not contain any digits.
(In reply to taozhijiang from comment #2) I'm not going to try and code for arbitrary strings passed to genkernel. If you can create a patch that actually works for this, you are welcome to send it upstream.

I'll reopen this, but note that any changes need to be reviewed and accepted upstream.
Additionally I discovered another failing behavior discussed at: https://forums.gentoo.org/viewtopic-t-1051118.html With sys-boot/grub-2.02_beta2-r9 I am experiencing following situation: 1. ~# ls /boot zeus boot # ls -la total 22560 drwxr-xr-x 5 root root 4096 Sep 7 15:57 . drwxr-xr-x 23 root root 4096 Jul 14 06:09 .. drwxr-xr-x 2 root root 4096 Aug 23 11:12 backup drwxr-xr-x 6 root root 4096 Sep 7 15:47 grub -rw-r--r-- 1 root root 2644340 Sep 7 15:57 initramfs-genkernel-x86_64-4.4.6-gentoo -rw-r--r-- 1 root root 2645712 Sep 7 15:42 initramfs-zeuskernel-x86_64-4.4.6-gentoo -rw-r--r-- 1 root root 0 Aug 13 21:22 .keep -rw-r--r-- 1 root root 5339808 Sep 7 15:57 kernel-genkernel-x86_64-4.4.6-gentoo -rw-r--r-- 1 root root 5339808 Sep 7 15:42 kernel-zeuskernel-x86_64-4.4.6-gentoo drwx------ 2 root root 16384 Dec 20 2013 lost+found -rw-r--r-- 1 root root 3525519 Sep 7 15:57 System.map-genkernel-x86_64-4.4.6-gentoo -rw-r--r-- 1 root root 3525519 Sep 7 15:42 System.map-zeuskernel-x86_64-4.4.6-gentoo So there is file set with supported naming and other with unsupported in the moment. Originally the behavior reported by taozhijiang didn't discover this. In my case wrong ram disk is detected for specific kernel(providing just snippet): Found linux image: /boot/kernel-zeuskernel-x86_64-4.4.6-gentoo Found initrd image: /boot/initramfs-genkernel-x86_64-4.4.6-gentoo So this should be also kept in mind when changing the string matching patterns, that they don't overlap.
Is there any point to add to the genkernel docs this limitation if you use --kernname? It seems odd to not be able to use any digits, but at least warning folks someplace would be helpful.
