What about a boot parameter like live-media=only=udev=<udev match criteria>

[Philippe Lelédy <debian@leledy.fr>]

Hi,

I RFC for a boot parameter that I am about implementing:

live-media=only=udev=<udev match criteria>

where <udev match criteria> is the part of an udev/rule that do 
selection of a /sys/ device.

It gives the user full control of which usb partition should hold live/ 
; more or less fine grained criteria can be used.

Threafter, /scripts/live will do an exclusive mount on the dev node 
created by this rule, immediately after this dev node being created by 
udev, either with a udevadm settle or a inotifywait.

Thanks for comments.
