[gentoo-user] rc_coldplug - what to use instead of it?
Hi, when moving GenToo to similar hardware by cloning / and /usr I had strange effects like renaming eth0 to eth1 unless I got the hint by some helpful guy on this list to set (in /etc/rc.conf) rc_coldplug=NO during the first boot switching back to rc_coldplug=YES for future boots. Now, that rc_coldplug has gone, what can I do instead? Many thanks for hint, Helmut. -- Helmut Jarausch Lehrstuhl fuer Numerische Mathematik RWTH - Aachen University D 52056 Aachen, Germany

is a cleaner way.
I guess you need to use udevinfo to get the important information
about /sys/class/backlight/asus-laptop/brightness and then write up a
rule, slap it into a file in /etc/udev/rules.d/ and enjoy your new
permissions. :) I don't have that device on my system so I can't
really suggest anything more specific.
Here's a udev rules HOWTO that might help:
http://www.reactivated.net/writing_udev_rules.html
(specifically Controlling permissions and ownership)
Good luck :)
Paul
It looks like I cannot simply write a rule to change that permission...
After experiencing some failures I guess that udev rules can change
permissions on /dev/ files, but not on /sys/ files...
This is my case:
# udevadm info -a -p /sys/class/backlight/asus-laptop/
looking at device '/class/backlight/asus-laptop':
KERNEL==asus-laptop
SUBSYSTEM==backlight
DRIVER==
ATTR{bl_power}==0
ATTR{brightness}==5
ATTR{actual_brightness}==5
ATTR{max_brightness}==15
And this is the rule I added in /etc/udev/rules.d/10-local.rules
KERNEL==asus-laptop, SUBSYSTEM==backlight, GROUP=video, MODE=0660
After a reboot I still get this:
# ls -la /sys/class/backlight/asus-laptop
total 0
drwxr-xr-x 3 root root0 2009-01-09 15:18 .
drwxr-xr-x 3 root root0 2009-01-09 15:18 ..
-r--r--r-- 1 root root 4096 2009-01-09 15:18 actual_brightness
-rw-r--r-- 1 root root 4096 2009-01-09 15:19 bl_power
-rw-r--r-- 1 root root 4096 2009-01-09 17:02 brightness
-r--r--r-- 1 root root 4096 2009-01-09 15:18 max_brightness
drwxr-xr-x 2 root root0 2009-01-09 15:19 power

-rw-r--r-- 1 root root 4096 2009-01-09 15:18 uevent
Googling a bit I found some solutions [1] [2], but all of them are
changing the permissions at every
boot. It works, but it looks to me a bit unclean...

You could use iptables to block all traffic headed to port 80 with exceptions for the domains you need. Would that cause problems with fetching packages for emerges? - Grant

It doesn't matter if it is put there by oldconfig or menuconfig or some other config. It's either there built in, as a module or it is not there. Really simple. Well, I would have thought the same up until a week or so ago, but my conspiracy theory is that the 2.6.27-r7 gentoo kernel (don't know about the vanilla version) broke things. In my case I couldn't get my sound card to work - alsa would error out not recognising my card. I have been using oldconfig for years now, but also tried menuconfig just in case - of course it made no difference. Filed a bug and it was suggested to me that I try building the alsa drivers as modules. I tried it on for size and guess what, it worked!
