I'm running a headless server installation of arch linux. The high rate of kernel upgrades caused me some maintainance headache and I therefore wish to switch to the lts kernel.
I already installed the linux-lts
and linux-lts-headers
packages. Now, I got both kernels installed but I'm a bit clueless how to continue from here. The docs explain:
[...] you will need to update your bootloader's configuration file to use the LTS kernel and ram disk:
vmlinuz-linux-lts
andinitramfs-linux-lts.img
.
I already located them in the boot section:

total 85M

4,2M -rw-r--r-- 1 root root 4,2M 19. Mai 21:05 vmlinuz-linux-lts
Now, I already found entries pointing to the non-lts kernel in the grub.cfg
but the header tells me not to edit this file. It points me to the utility grub-mkconfig
instead but I can not figure out how to use this tool to tell grub which kernel and ramdisk to use.
How to switch archlinux with grub to the lts kernel? What else do I have to be cautious about when switching the kernel?
