Draft: RFC: Add virtual initramfs-generator package
Presently, many Alpine package depend directly on mkinitfs (e.g. grub,
syslinux, or linux-lts itself). However, these package do not
specifically need mkinitfs but simply a tool to generate an initramfs
image. By providing a virtual initramfs-generator package we can
abstract from the specifics of a initramfs generation tool and allow
usage of Alpine with initramfs images not generated by mkinitfs.
The initramfs generation tool simply needs to provide /boot/initramfs-$flavour.
This is a prerequisite for adding support for the booster initramfs (see #13088 (closed)) but should also allow adding packages for other initramfs generation tools.
