Description Poncho 2014-01-17 09:38:16 UTC

currently, it's not possible to add a bootloader entry for 3.12.8 and 3.12.8.old with systemd's kernel-install.

3.12.8:
- vmlinuz: /boot/vmlinuz-3.12.8
- systemmap: /boot/System.map-3.12.8
- config: /boot/config-3.12.8
- modules: /lib64/modules/3.12.8
- build: /usr/src/linux-3.12.8
3.12.8.old:
- vmlinuz: /boot/vmlinuz-3.12.8.old
- systemmap: /boot/System.map-3.12.8.old
- config: /boot/config-3.12.8.old
- modules: /lib64/modules/3.12.8
- build: /usr/src/linux-3.12.8

above files are created by make install and make modules_install in the kernel build directory.

Where is the problem?

# kernel-install add 3.12.8.old /boot/vmlinuz-3.12.8.old
# kernel-install add 3.12.8 /boot/vmlinuz-3.12.8

should work fine. Of course you might have to correct the initramfs, because it might fail, because there is no /lib64/modules/3.12.8.old

I guess you manually copied /boot/vmlinuz-3.12.8 to /boot/vmlinuz-3.12.8.old.
So, why can't you do the same with the bootloader entries and correct them?

I did not copy them manually. installkernel from debianutils does this by default.
The grub2 scripts added an entry for the *.old kernel automatically (using the initramfs from the non*.old kernel with the same version).
