Execute Script On Kernel Update

I can't find a current thread on this topic, but have to believe it has been asked before...

What I want to do is every time pacman updates the stock arch kernel, have pacman run a script after the upgrade.  Is there a hook in pacman to do this, but only after a new kernel?

It seems that it should be possible to set up a monitor within pacman that says, "if package X is updated, then run script xxx".  This would be great as then when the kernel is updated my VBox Additions could be upgraded or any one a 100 other scenario's.

Thanks.

This is currently being discussed on the pacman-dev list.  A draft proposal is available here: http://wiki.archlinux.org/index.php/Use … cman_Hooks

Re: Execute Script On Kernel Update

pretty sure there's no default pacman functionality for this.  just thinking real quick, you could do something like this as a workaround:

pacup() {
  sudo pacman -Syu | tee /tmp/updates.$$

  if grep -q "upgraded kernel26" /tmp/updates.$$; then
    echo "kernel was upgraded, doing... whatever"
    # do whatever here...
  fi

  rm /tmp/updates.$$
}

add that as a bash function, it'll be normal -Syu if kernels not upgraded and it'll run your stuff if it is.  i don't really see any issues with doing this... but wouldn't be surprised if there were, and i'm sure someone here will correct me.
