[SOLVED] initcpio not being generated after kernel upgrade with pacman

The pacman hook for generating a new initcpio when there is a kernel update no longer seems to be working for me. I see its running something because it prints ( 6/15) Updating linux initcpios... but there is never a initcpio image in /boot after it runs.

Re: [SOLVED] initcpio not being generated after kernel upgrade with pacman

With what kernel package and what mkinitcpio package?

Re: [SOLVED] initcpio not being generated after kernel upgrade with pacman

I finally figured it out. The issue is /etc/mkinitcpio.d/linux.preset no package seems to own that file, but it was empty for some reason. It needs to have this in it:

# mkinitcpio preset file for the 'linux' package

ALL_config="/etc/mkinitcpio.conf"
ALL_kver="/boot/vmlinuz-linux"

PRESETS=('default' 'fallback')

#default_config="/etc/mkinitcpio.conf"
default_image="/boot/initramfs-linux.img"
#default_options=""

#fallback_config="/etc/mkinitcpio.conf"
fallback_image="/boot/initramfs-linux-fallback.img"
fallback_options="-S autodetect"

Re: [SOLVED] initcpio not being generated after kernel upgrade with pacman

/etc/mkinitcpio.d/linux.preset should have been created by the pacman hook /usr/share/libalpm/hooks/90-mkinitcpio-install.hook
I would suggest checking /var/log/pacman.log to see if the hook was called and if it was if it failed.

Re: [SOLVED] initcpio not being generated after kernel upgrade with pacman

I'm bumping this thread since I happened to have the very same issue and solved it very simply: I deleted the empty linux.preset file syamajala mentioned, and re-run the install of the linux package. The linux.preset file was correctly generated and all worked fine from there.

As to why and how the linux.preset file ended up being empty in the first place, I have no idea.

I love you tbw. Same problem here and same solution, and as you, I have no idea why my linux.preset file was empty. THANK YOU A LOT.

Re: [SOLVED] initcpio not being generated after kernel upgrade with pacman

For the fellows that think that they can pacstrap without the "base" package, and somewhere along the way encounter:

(11/12) Updating linux initcpios...
/usr/share/libalpm/scripts/mkinitcpio: line 31: sed: command not found
==> WARNING: Preset file `/etc/mkinitcpio.d/linux.preset' is empty or does not contain any presets.

That will result in having an

empty /etc/mkinitcpio.d/linux.preset file

To resolve this situation, it might be wise to install the "base" package after all. Delete the preset.

# rm /etc/mkinitcpio.d/linux.preset

And when inside the arch-chroot already run

# pacman -S linux 

to re-generate /etc/mkinitcpio.d/linux.preset with the correct default content.

Re: [SOLVED] initcpio not being generated after kernel upgrade with pacman

Just out of curiosity, would it not make sense for the mkinitcpio pkg itself to have sed as a dependency explicitly listed ? This way, if base is not used for whatever reason, then at least it will get pulled in as part of the dependency resolution. The bonus is that dependency resolution gets more granular and detailed.

Without base, it isn't an Arch Linux install:

base package description wrote:

Minimal package set to define a basic Arch Linux installation
