Problem with udev-161 and isdn capi device nodes

Problem with udev-161 and isdn capi device nodes

[Silvan Minghetti]

Hi

I'm having a problem with udev >= 154, as it warns on NAME= values 
different from the kernel provided names, as done per changeset

http://git.kernel.org/?p=linux/hotplug/udev.git;a=commitdiff;hucb1ac51ea0176926c749bd0f22c19ce8b20e5f

The problem is, with the following isdn capi rules (which were removed 
from udev anyway), udev is not able to create the wanted devices, 
because of a missing directory (/dev/capi), which has to be created 
beforehand:

SUBSYSTEM="capi", KERNEL="capi", NAME="capi20", GROUP="dialout"
SUBSYSTEM="tty", KERNEL="capi[0-9]*", NAME="capi/%n"

so, instead of /dev/capi20 we now get /dev/capi
and /dev/capi0 instead of /dev/capi/0

Is this here to stay or is this going to be changed in the kernel? The 
new layout breaks quite a few apps/libs...

It needs to be changed in the kernel. It's rather trivial, but I don't
know if anybody is working on this at the moment. I guess people have
moved to mISDN, and that's why this hasn't really come up so far?
