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

qwijibow · 07-08-2004, 09:55 AM

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

well,,,, 'top' shows udevd is running, but i find no mention of udev in the config file i used to compile m 2.6.7 kernel.. i will play with the udev config anyways.

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
