man page initrd (4) is outdated and misleading

Binary package hint: manpages

How to reproduce :
===============
type
$ man 4 initrd
or
$ man initrd

What happens
============

Explanations are:
 - about file /dev/initrd : /dev/initrd does not exist anymore
 - about kernel 2.4 boot process : current kernels are 2.6
 - about lilo boot loader : grub has replaced lilo

What was expected
===============

See explanations:
 - about file /boot/initrd.img-(version)
 - about kernel 2.6 boot process
 - about grub 2 integration
OR
See nothing.

Way to fix
========

Remove file /usr/share/man/man4/initrd.4.gz
from "manpages" package
OR
Rewrite this page
