ok

yep, not that i use them much,but i'll at least make some progress on the
udev.rules
and i may try to push them to the mandrake kernel package, which will
probably
return more responce :-)

same as previous comment, but i do listen music all the time :-)

right, why not just upload all the patches you know of or have handy,
to kernel.org/.../hotplug/ and add a big fat note they are experimental
/* may be experimental at what level too, (applies, boots, runs, oopses) */
and add a small coment in the FAQ

this will probably spare you some time answering dumb question
/* and would spare some time google-ing for others too :-) */

hm, i was browsing the thread a while ago, but didnt get it fully
there were some issues with using 2 rules for one device,
do hard disks/ tapes/... also has such a type file ?
do only scsi ones have it ?
i was thinking of 

[address] type="hd" .... name1
[address] type="cd" ....name2

wait a bit :-)
it seems that some special devices do use "disk",
while scsi/ide hard's use "disc"
/* devfs has THE naming policy, doesn't it?:)  */
 
I think Arnd is looking into the issue

best,
