Kernel 2.4.31 and udev

merchtemeagle · 04-03-2006, 02:16 PM

I've read in the udev README file that one needs the 2.6 kernel to use udev. I use the standard kernel that comes with Slackware 10.2 yet:

$ ps aux | grep udev
root 180 0.0 0.0 1384 384 ? S<s Mar30 0:00 udevd

Why is this daemon running?

this daemon creates /dev files when they are needed, that way you don't have several hundered blank files. if you don't want it to run, do this as root.
chmod 644 /etc/rc.d/rc.udev

i had problems with mine so i disabled it. That was about 4 months ago, so far no problems

Hmm, I don't know. If /dev files are only created when they are needed, how come I've got alot of such files?

$ ls -l /dev/ | wc -l
2575

Udev does not work properly for me neither with default Slackware 2.4 kernel, neither with my 2.6 kernel.

2.4 does not use udev. So, if you are running a 2.4 kernel, you can safely turn the udev service off at startup (on some udev packages it's enabled by default, hence the service is running).

chmod -x /etc/rc.d/rc/udev

Without udev (which mounts a virtual file system on /dev), you are relying on the Slackware package devs which provides devices nodes for every possible device (regardless of whether it exists or not).

Thanks a lot for that clarification!
