[SOLVED] Systemd boot not using default entry for kernel.

I have the following config files for systemd-boot

$ cat /boot/loader/entries/arch.conf
title	Arch Linux Standard
linux	/vmlinuz-linux
initrd	/amd-ucode.img
initrd	/initramfs-linux.img
options	root=PARTUUID=8b3ea6fe-307d-40bd-af48-a9098594be1e rw

$ cat /boot/loader/entries/xanmod.conf
title	Arch Linux Xanmod
linux	/vmlinuz-linux-xanmod
initrd	/amd-ucode.img
initrd	/initramfs-linux-xanmod.img
options	root=PARTUUID=8b3ea6fe-307d-40bd-af48-a9098594be1e rw

$ cat /boot/loader/entries/zen.conf
title	Arch Linux Zen
linux	/vmlinuz-linux-zen
initrd	/amd-ucode.img
initrd	/initramfs-linux-zen.img
options	root=PARTUUID=8b3ea6fe-307d-40bd-af48-a9098594be1e rw

$ cat /boot/loader/loader.conf
default xanmod.conf
timeout 3
console-mode max

From what I understand from the wiki on configuration ( https://wiki.archlinux.org/title/System … figuration ) this should be loading the Xanmod kernel by default on boot. However, it always loads the Zen kernel by default instead. The Xanmod kernel works fine if I manually select that entry during boot but it doesn't seem to default to it.

Do you see anything missing from here that could be causing this not to work?

Re: [SOLVED] Systemd boot not using default entry for kernel.

The entry name is without the .conf iirc so your default would just be xanmod in your loader.conf (though I do see now that the wiki includes it but I'm almost certain it's without...)

Something that could also interfere here, you can use the d key to explicitly enforce a default (signified by an arrow in the boot menu) that always takes precedence in which case you'd want to clear it with d again (... or just use that to enforce xanmod)

Re: [SOLVED] Systemd boot not using default entry for kernel.

If you have a UEFI variable for LoaderEntryDefault, that will override the default set in the config file. See the tip in the configuration section of the page you linked.

Re: [SOLVED] Systemd boot not using default entry for kernel.

Thanks, it was a matter of the .conf in the loader.conf

It works just fine with:

$ cat /boot/loader/loader.conf
default xanmod
timeout 3
console-mode max

Old systemd-boot on your ESP? Check `bootctl status`.

Re: [SOLVED] Systemd boot not using default entry for kernel.

234 is indeed somewhat old. I'm pretty sure the change (to require .conf) was somewhere between 240 and 245, and we're at 249 now. So if you `bootctl update`, you want to update loader.conf at the same time.

Re: [SOLVED] Systemd boot not using default entry for kernel.

Thanks for the tip on updating the bootloader. I hadn't touched that since I switched to systemd-boot over 4 years ago on this machine and I'd been using rEFInd on this machine for the 4 years before that.

I read up on that section in the Wiki and now I have it updating with Pacman hooks.
