Bug#522382: live-initramfs: using 'persistent=nofiles' parameter don't find persistent: some details

[Philippe LeléŽdy <debian@leledy.fr>]

Debian version 5.0.1

I made some investigation around this bug, with some comparaison between 
boot cheatcode "debug persistent" versus "debug persistent=nofiles".

Here are the results:
----------------
grep  "+ /lib/udev/vol_id -l " live.persistent=nofiles.log

+ /lib/udev/vol_id -l /dev/sda
+ /lib/udev/vol_id -l /dev/sdb
+ /lib/udev/vol_id -l /dev/scd0
+ /lib/udev/vol_id -l /dev/sda
+ /lib/udev/vol_id -l /dev/sdb
+ /lib/udev/vol_id -l /dev/scd0
+ /lib/udev/vol_id -l /dev/sda
+ /lib/udev/vol_id -l /dev/sdb
+ /lib/udev/vol_id -l /dev/scd0
+ /lib/udev/vol_id -l /dev/sda
+ /lib/udev/vol_id -l /dev/sdb
+ /lib/udev/vol_id -l /dev/scd0

It is clear that this behaviour is buggy, disk partitions are never 
scanned, only the whole device.

But with "persistent" alone disk partitions *are* scanned
