[arch-general] dhcpcd not working after install from custom iso

[Christian Demsar]

I had internet connection when installing from an iso I built using the
archiso tools, but dhcpcd isn't connecting any more (starting via
sytemd). I've also had internet access in previous installs of archlinux
and FreeBSD, so I don't think there's anything wrong with the hardware.

[dmesg output] http://pastebin.com/vtVRid1Y
[ip link output] http://pastebin.com/gaZxUCmf

The device I'm using is listed as enp2s0. It hangs, even though it's set
up (pastebin for proof). Waiting for carrier? I also noticed that at the
bottom of my dmesg, it reports only IPv6, not IPv4. Is this normal
behavior? I think my network only supports IPv4, for dhcp anyway.

Since I have to register the addresses of the NICs with the ISP, only
enp2s0 should hypothetically be able to connect, not enp1s0. This is
also the first time I've had a problem with dhcpcd.

If it makes a difference, I built a custom iso (base) and dropped the
bcache-tools package in /etc so I could set that up. I made no other
modifications to the bulid.

dhcpcd is at version 6.6.4-1 and is fully up-to-date.
