4.1 - How To Select A Kernel As Default?​

Step 1: Open the loader.conf file

sudo subl /efi/loader/loader.conf

Step 2: Edit the default field.

There is a default entry inside /efi/loader/loader.conf that determine the default boot entry.

On a new install, it will look something like this:

default 665eca4ae83246df8ec17d1cbc6a1763*

That first string of characters is you entry token which identifies the install. That is important if you are dual-booting with another Linux, otherwise it can be replaced with *. That line supports wildcards and so if you want to boot the LTS kernel by default you could use something like this:

default 665eca4ae83246df8ec17d1cbc6a1763*lts.conf

Alternatively, if you want to boot the mainline kernel by default, something like this should work:

default 665eca4ae83246df8ec17d1cbc6a1763-*-arch?-?.conf

These changes will take effect on the next reboot and nothing else is required except modifying the file.
