You ran that as root, right? Hm, try running the udev-test.pl script in that directory. Let us know if the tests there pass or not.

You can build udev on any kernel. _but_ the test.all script will _not_ show anything in /udev if you are not on a 2.6.0 kernel. That's probably the problem. The udev-test.pl script will work on any kernel, it uses its own fake sysfs tree. > - I didn't switch my system to kernel 2.6.0 and udev, I am trying to > test it within initrd (Initial Ram Disk), so what I have is a > subdirectory in my home directory, where I installed busybox, bash, > insmod, modprobe, hotplug scripts and udev, plus the needed shared > libraries in /lib.

That's a requirement. thanks, greg k-h ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
