[gentoo-user] Editing /etc/init.d/net.eth0 to pass options to dhcpcd

[Michael Sullivan]

Is there a way that I can edit /etc/init.d/net.eth0 so that when it
calls dhcpcd to get an IP address, it doesn't overwrite my domain name
or my /etc/resolv.conf file?  I looked at /etc/init.d/net.eth0, but
could not find anyplace where it actually called dhcpcd...

The actual call to dhcpcd is in /lib/rcscripts/net/dhcpcd.sh.  But you
really don't want to edit that script.

You should read /etc/conf.d/net.example.

If you *really* want direct control over the dhcpcd options:
-------
# For passing custom options to dhcpcd use something like the following.  This
# example reduces the timeout for retrieving an address from 60 seconds (the
# default) to 10 seconds.
#dhcpcd_eth0="-t 10"
------

But, probably what you really want is the generic "nodns" option:

------
# GENERIC DHCP OPTIONS
# Set generic DHCP options like so
#dhcp_eth0="release nodns nontp nonis nogateway nosendhost"

# This tells the dhcp client to release it's lease when it stops, not to
# overwrite dns, ntp and nis settings, not to set a default route and not to
# send the current hostname to the dhcp server and when it starts.
# You can use any combination of the above options - the default is not to
# use any of them.
------
