I asked because you could try and see if networkd can acquire a lease by
itself, without dhcpcd (I don't expect it to). Also, could you run dhcpcd with
"-d -t 0" (debug output, no timeout) to see what it's doing?

I have seen a similar issue with networkd and bonding of interfaces. It turned
out that the way networkd works with links is racy, so in ~70% of boots dhcp
lease attempts failed both via networkd and dhcpcd. The only solution which I
found was to use netctl (should be availabel on ALARM) where you can explicitly
specify a precise order in which links should be managed.
