[SOLVED] How to restart udevd without rebooting

markush · 10-20-2009, 03:57 PM

Hello together,

I've configured my scanner for scanning over the network (as I've described in this thread: http://www.linuxquestions.org/questi...etwork-761212/).
Since I had to fiddle around to find the adequate udev-rules I had to restart udevd several times. But I did not know if and how it's possible to restart the udev daemon, so I rebooted my computer several times. Now my question: is it possible to restart udevd without rebooting the system?

The very first hit for "gentoo restart service" explains it pretty clearly.

http://www.gentoo.org/doc/en/handboo...?part=2&chap=4

Just run "/etc/init.d/servicename restart".

I'm not sure if that will force udev to re-run it's rules though. You may have to try using the "trigger" option in udevadm to do that.

Hello David the H.

thanks for the answer, but this won't work with Gentoo.

Sorry that I did not explain what I've tried before posting.

Code:

NoteBook ~ # /etc/init.d/udev restart
 * The udev init-script is written for baselayout-2!
 * Please do not use it with baselayout-1!.

I ended up to find out what a baselayout is. But since I'm pretty new to Gentoo I've not understood the explanation.
It maybe that restarting udev on a running system is as dangerous that rebooting is the better (saver) choice and I started this thread to get an answer about that.

Baselayout is a package that installs the basic init scripts and some config files. A bit part of the init process of a default Gentoo system goes there. The udev script in there is for baseleyout-2.x and you seem to have 1.x installed.

With either version, "devadm control --reload-rules" should instruct the daemon to read the rules again.

Thanks very much for the answer, I think this is exactly what I've been looking for.
