My understanding of udev is that devices are created in /dev when the are needed (i.e.; module is loaded, device is activated).

My experience with udev has been pretty positive in all but one instance, the raw1394 device. I have to manually create this device before I can use the digital camrecorder.

While creating the device is pretty easy, if I reboot the system (new kernel) the device disappears and I have to recreate the device before I can use Kino.

This problem has been nagging at the back of my mind for some time now. It seems to be the case with both Slackware and Debian; and I have not invested much research time. I'm wondering if this is a udev or hotplug issue.

I used to have this problem with nVidia devices not being created on boot. To use the nVidia accellerated video drivers I needed /dev/nvcntl or some such. Some people suggested doing a modprobe in rc.local to create the devices.

There was also a directory where I could create the devices and udev would copy them over on every boot. I can't remember details, but I'll check my E-mil archives when I get home. This was on Fedora, of course, but the info still might help.

I'm guessing it's a udev issue, and although there's documentation out there, I've found it confusing. I know there's a way to have udev create the devices you want and name them like you want.

Here's a link that might help. http://www.linux1394.org/faq.php#udev It's worth a shot.
