Booting up without ethernet cable plugged in - hangs[Solved]

[jellysandwich]

My setup works fine with the cable plugged in, but if I
take it out, my computer hangs at "Running dhcpcd ...".

Is there a way to make it work both with and without
the cable?

you could specify a run level labelled "offline" which you could configure in order to do everything your system does except run dhcpcd. Or you could try pressing control c when it starts trying to run dhcpcd (I dunno if it works, never tried. But I think your best bet will be to try and get an "offline" run level going and boot off of that. There's a section on it in the other sections of the Gentoo Installation Manual.

I don't know how long you've left it, but dhcpcd takes at least a minute to time out if there's no network. Have you left it for a few minutes to see if it's really hanging?

Put a -t option in /etc/conf.d/net
You can manually override Dhcpcd timeouts.

if you have mii-tool installed or ethtool you can use the preup() part of the /etc/conf.d/net file in the example we have this:
#preup() {
# # Test for link on the interface prior to bringing it up. This
# # only works on some network adapters and requires the mii-diag
# # package to be installed.
# if mii-tool ${IFACE} 2> /dev/null | grep -q 'no link'; then
# ewarn "No link on ${IFACE}, aborting configuration"
# return 1
# fi
#
# # Test for link on the interface prior to bringing it up. This
# # only works on some network adapters and requires the ethtool
# # package to be installed.
# if ethtool ${IFACE} | grep -q 'Link detected: no'; then
# ewarn "No link on ${IFACE}, aborting configuration"
# return 1
# fi
#
# # Remember to return 0 on success
# return 0
#}

just uncomment the function name and the closing brace then uncomment the section for which ever tool you have installed on your system. This will not bring the interface up if there is no link.

Hope that helps.
