[gentoo-user] howto disable automatic net.eth0 configuration

[Justin Findlay]

I have a laptop computer with an ethernet port, and during bootup
dhcpcd gets invoked (twice) to configure a network connection on
'eth0'.  I have set

rc_hotplug="* !net.eth0"

in /etc/rc.conf and

RC_HOTPLUG="yes"
RC_COLDPLUG="yes"
RC_PLUG_SERVICES="!net.eth0"

in /etc/conf.d/rc (why do these files still both exist after 7 years,
especially as they contain duplicate configuration?)

I have also set 'noipv4ll' in /etc/dhcpcd.conf.  None of these
configurations prevent the double automatic initialization attempts
for net.eth0.

I would just unmerge dhcpcd, but it seems that NetworkManager needs an
external dhcp client.  What can I do to prevent this behavior?  What
have I missed?
