Hello everybody,
I added a hook to the initramfs whose install script added 'uname' by using add_binary. This resulted in major breakage and a kernel panicing on boot.
I suppose this is because there is a symlink from uname to busybox - with adding uname I killed the busybox binary. Is this ok by design or do we want to raise an error if something like this happens?
I created a patch (see attachment). Does this make sense?
Nope, it doesn't make sense. We overwrite a busybox symlink in the shutdown hook (cp, since we need the -a flag), and this isn't a problem.
Ah, my fault...
I added my hook before base in HOOKS array. This way bin was a real directory instead of a symlink to usr/bin.
Yup, I figured this is what you did. Incidentally, this particular user-induced bug should be fixed by a commit I just pushed a few hours ago: http://projects.archlinux.org/mkinitcpio.git/commit/?id=5f81d06e8b
