[Solved] grub-mkconfig not picking up new kernel

Hi,

I compiled the linux-lts kernel from source today, woohoo! First time compiling from source.  Fun!

I followed the Kernels/Compilation/Traditional - Archwiki.  No problems at all in the Build Configuration and Compilation & Installation steps.  The issue is that when I try to add the new kernel to grub.cfg

# grub-mkconfig -o /boot/grub.d/grub.cfg

it does not pick up my new kernel.  Here's the contents of /boot:

% ll /boot                                                                                                                                                   ~

lrwxrwxrwx  1 root root       26 Aug 31 17:13 System.map -> /boot/System.map-linux-lts

drwxr-xr-x  2 root root     4096 Aug 31 17:26 grub

-rw-r--r--  1 root root  3982880 Aug 13 22:43 vmlinuz-linux

Here's the output of grub-mkconfig:

# grub-mkconfig -o /boot/grub/grub.cfg                                                                                                                  ~
Generating grub configuration file ...
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
Found fallback initramfs image: /boot/initramfs-linux-fallback.img
done

I've tried a bit of googling, checking journalctl, but haven't come up with anything, I've also retraced my steps in the wiki process about 3-4 times.  I'm hoping someones bumped into this before, maybe I'm missing something obvious?

Thanks for your time!

Re: [Solved] grub-mkconfig not picking up new kernel

# cp -v arch/x86/boot/bzImage /boot/vmlinuz-YourKernelName

According to your "ls" your lts kernel is named "vmlinux-linux-lts" -- try renaming it "vmlinuz-linux-lts"

lullllzlzl.  Oh man, I'm not even going to deprecate myself here, or make excuses. To be perfectly honest, I'm glad it was a typo and not a real issue.  I can't thank you enough for pointing this out.  Gladly marked solved.
