[arch-general] RFC: declarative reference to installed kernel(s) and its modules and vmlinuz image

Currently it's quite complicated to make the reference from an installed kernel package(s) to it's files (the kernel image and modules), except by either invoking `pacman -Qlq linux | grep vmlinuz$` or some heuristics like what mkinitcpio does. So the proposal is that every kernel package should also include a symlink in /var/lib/kernel/<pkgname> to the path in /usr/lib/modules/<kver>/. for ex. currently that would be: /var/lib/kernel/linux -> /usr/lib/modules/5.15.7-arch1-1/ /var/lib/kernel/linux-lts -> /usr/lib/modules/5.10.85-1-lts/ Benefits of this approach would be for tools like mkinitcpio, or sbctl, which can declaratively refer to the kernel modules and the vmlinuz image, by just knowing the package name. -- damjan
