Udev is creating too many devices

Question

I have built a kernel and root file system for a vortexS86 processor using OpenEmbedded. When it comes up I have hundreds of device entries in the /dev directory. This include such items as

digi_ctl(0-255) pty(a-z)(0-f) ttyD(0-255) ttyMX(0-255)

etc.

I am trying to figure out whether udev is creating all of these and if so where. If it isn't udev - where are they coming from?

I can find no rules under either /lib/udev/rules.d or /etc/udev/rules.d that contain any reference the device types.

Any ideas?

Thanks

Dave

Answer 1

I do believe device drivers can create device files in /dev/ without there needing to be udev rules for them, espectially ptys and ttys and stuff.

Are these files bothering you for some reason or are you just wanting to keep /dev sparse, I'm sure you can tell udev NOT to create the default entries. use something like:

udevinfo -q all -n /path/to/device 

to find out more info about it
