It seems to work just fine.
mtdchar I see it loaded automatically anyway due to char device alias.

So this rules does the trick:

ACTION!="add", GOTO="mtd_probe_end"
KERNEL="mtd*ro", IMPORT{program}="mtd_probe --export $tempnode"
LABEL="mtd_probe_end"


And all I have to do is to write the mtd_probe

My current stub mtd-probe is:


#!/bin/sh
# $1 = device node
echo "MODALIAS=sm_ftl"
echo "ID_DRIVE_FLASH=1"
