Bug#299103: initrd-tools: mkinitrd tries to use devfs in 2.6 series kernel

[Jesús Rojo Martínez <jrojo@ehas.org>]

Package: initrd-tools
Version: 0.1.77
Severity: important
Tags: patch

I use RAID disks, including the root partition. Thus I used and initrd image to boot correctly.

However, when I use mkinitrd from the initrd-tools, it fails to boot because it doesn't find the root partition,
because mkinitrd uses devfs (and obviusly, I don't have devfs in the 2.6 kernel).

I send a patch that works fine for me (and it should work for everybody). The patch could be better, concretaly
the part that detects other RAID partitions:

  - Don't copy /etc/mdadm/mdadm.conf, just generate it with some like:

	echo "DEVICES partitions" > $INITRD/$MDADMCONF
	mdadm -D --scan >> $INITRD/$MDADMCONF

  - Moreover, with the information generated with those commands, read the devices needed for
    "automatic" adition to the initrd (echoes them to >&4).


Thanks a lot and sorry about my poor english.
