udev initscript for testing

[nestu]

Hello udev users ;)
I've attached a udev initscript that florin and I need to 
test. It works for me and not for florin, so we need a 
little more testing, to see what's wrong (we don't seeem to 
find the problem). If we get good feedback, we'll add it to 
udev module, and bump to 021. The attached udev must go in 
whatever placement your lin'ed udev put it, because it could 
have been installed under /etc/rc.d/init.d/ or /etc/init.d/ 
( *please* check lvu install udev to know where it was placed).
TIA,
nestu && florin
