How can I execute a command after kernel-upgrade/mkinitcpio
Because of the archlinux specific kernelnaming-policy there's a problem when using grub2. The created menu looks nasty because grub-mkconfig can't find the proper kernel-version. (Bugreport: https://bugs.archlinux.org/task/25453)
Even if this is fixed we need to recreate the grubconfig always when a new kernel-version is installed.
What I want now is executing grub-mkconfig after each kernel-installation/mkinitcpio, without repackaging the kernel. Is such a hook possible?

Re: How can I execute a command after kernel-upgrade/mkinitcpio
mod note: I fixed the url to the bug report for you by moving the ')' outside of the tags.
One possible workaround, disable the linux detection script (in /etc/grub.d) and make your own script which echoes the Arch entries as you want them to be.

Rorschach, I added a solution in the bugreport you posted. It might be ugly but it works

Re: How can I execute a command after kernel-upgrade/mkinitcpio
I don't recreate grub.cfg every time the kernel is updated. Why is this supposed to be necessary?

Re: How can I execute a command after kernel-upgrade/mkinitcpio
I haven't looked at this too closely, but you should be able to construct a bash script using inotify-tools to watch your vmlinuz files and run your custom commands when vmlinuz changes.

This is not necessary unless Versioned Kernel Installs are supported by pacman. I have added a new patch to https://www.dropbox.com/sh/jth3mchm3hob … src.tar.gz that solves the issue. No need for pacman or mkinitcpio hooks (for now).

This article was written for debian/ubuntu but should work for arch Run Command On Kernel Update. Hope it helps.
