Yea, _you_ can't imagine this. :) But Kernel developers can... . > Reading through the documentation that I've found about udev, your > main points seem to be about: > > - udev vs devfs > - running out of device major/minor numbers > - not having to worry about major/minor numbers > > For me, the first point is moot because I don't use devfs.

Every new device needs a unique number, that _no other_ device uses. As more and more devices are developed, we are running out of device numbers. (well, that may take a while with 32-bit device numbers, but it may appear so). > So, Greg, is there _any_ reason why I'd want to be using udev? (Hm, I'm not Greg, but...) Because it's cool. :) No, you're right. I am not going to use udev or devfs on my server for example. The reason is quite simple. This server will be running linux-2.4 until it dies and I will never add some more device to it. So there is no point of using udev or devfs on it. I know the hardware, create all nodes for it and it runs (without all the problems devfs and udev still provide). But on my main Computer I am going to use udev, because I love it's flexibility. _You_ have to decide if you need udev or don't. Nobody else can decide it for you. - --=20 Regards Michael Buesch [ http://www.tuxsoft.de.vu ] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQE/9WtsFGK1OIvVOP4RAoD2AKCMOAVWp226hzMQxju9Yo7t8uO7FQCguSJe 7XksJs4zqwCeFyBQkcBOn98=3DchS9 -----END PGP SIGNATURE----- ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
