SOMTHING keeps changing file permisons and sym links in /dev !


seemingly randomly, somthing keeps changing the file permissions of the folowing files

/dev/nvidia0
/dev/nvidia1
/dev/nvidiactl

/dev/hdc
/dev/hdd

also, it keeps removing the symlinks..
/dev/cdrom -> /dev/hdc
/dev/cdrom1 -> /dev/hdd

and creating the link
/dev/cdrom -> /dev/hdd (the wrong cd-drive)

im using slackware 10.

the permissions are so restrictive, i cannot play OpenGL games, or Audio CD's

edit: lol, forgot to ask.. Whats wrong ? what keeps doing it? and how do i stop it ?

I would think that is the behaviour of the udev feature with 2.6 kernel.

The permissions can be set in
/etc/udev/permissions.d/udev.permissions

And the links can be created like this :
BUS="ide", KERNEL="hdc", NAME="%k", SYMLINK="cdrom"

at the top of the file
/etc/udev/rules.d/udev.rules

Of course, if you don't use kernel 2.6 or udev forget that

udev comes from udev package and uses the hotplug feature of the kernel to detect hardware and populates /dev node for it.

udev is a deamon not a module
