I set KNAME in /etc/genkernel.conf to sysv-genkernel. This worked, as genkernel all generated both a new kernel and a new initramfd. When using grub2-mkconfig, the command ignores and does not find the renamed initramfd. Rebooting causes a non bootable system Reproducible: Always Steps to Reproduce: 1. Uncomment and set KNAME in /etc/genkernel.conf - Use genkernel-next for plymouth support 2. genkernel all 3. grub2-mkconfig -o /boot/grub/grub.cfg 4. Reboot Actual Results: System will not boot. Expected Results: System should boot normally Portage 2.2.14 (python 2.7.9-final-0, default/linux/amd64/13.0/desktop/kde/systemd, gcc-4.8.3, glibc-2.19-r1, 3.17.7-gentoo x86_64)

If you give your kernels custom names, you are on your own for generating grub.cfg. If you want that to change, please send a patch upstream. I will be happy to backport anything they accept.
