Here's a new version of the patch. This one adds two packages akin to what upstart-sysv and systemd-sysv do:
1. busybox-init provides /etc/inittab and /lib/busybox/init. Then you can pass init=/lib/busybox/init in bootloader to use BusyBox init (GRUB even adds a menu entry if you edit SUPPORTED_INITS in /etc/grub.d/10_linux).
2. busybox-init-sysv provides the /sbin/init symlink (and /sbin/halt, etc) and Conflicts with other packages providing the same files.

busybox-initramfs provides a simple stand alone shell that provides
only the basic utilities needed for the initramfs.

+Description: BusyBox implementation of Init
+ BusyBox combines tiny versions of many common UNIX utilities into a single
+ small executable. It provides minimalist replacements for the most common
+ utilities you would usually find on your desktop system (i.e., ls, cp, mv,

+ their full-featured GNU cousins; however, the options that are included
+ provide the expected functionality and behave very much like their GNU
+ counterparts.

+ This package provides a minimalist implementation of Init, which can be
+ started by passing init=/lib/busybox/init parameter in your bootloader.
