Console had shown that it had forked too, no notice about carrier lost.

I gave up and sent a TERM signal to it:

Jul  9 01:39:20  dhcpcd[581]: received SIGTERM, stopping
Jul  9 01:39:20  dhcpcd[581]: ral0: removing interface

And started dhclient:

I want to use dhcpcd so I can try dhcpcd-ui more.

I also run with -d and see more details but no explanation on repeated 
"carrier lost" and "carrier acquired".
