raspberry pi wireless only

[psointu]

using a raspberry pi "b" and archlinux-hf-2013-07-22.img, i'd like to get the system to simply forget about the wired eth0 as i only want to use wlan0 from the get go.

a "cp /etc/netctl/examples/wireless-wpa /etc/netctl/wlan0" and then manipulation of /etc/netctl/wlan0 followed by a "netctl start wlan0" and a reboot seems to take care of the wlan0 side of things.

the issue seems to be getting this image to forget about eth0 ... it continues to try and bring it up and configure it via dhcp and spit back messages on the console when it inevitably fails to do so.

googling, man pages, etc all hint at things to try but none seem to accomplish what on the surface would seem to be a simple thing : disable eth0

any help would be much appreciated.

Obvious question, have you looked at what is enabled for systemd/netctl?

i'd spent a fair amount of time looking at netctl and couldn't get the desired result ... it appears that a

systemctl disable dhcpcd@eth0.service

did the trick ... what's odd is i'm almost certain i attempted the above earlier and got an error ... nevertheless, i seem to have my desired result now ... several reboots and ifconfig shows only lo0 and wlan0.

thanks for prompting me to re-examine things.
