Better is to cut the timeout. The relevant option to dhcpcd is "-t",
followed by a number indicating the seconds to timeout at. I'm using 5
and it is tolerable; since fixing my network settings a few days ago I
just let wlan0 and eth0 start up and they fail or don't as is
applicable. I don't think I've ever seen a DHCP connection that hadn't
connected in 5 seconds but eventually did; YMMV but ISTM that would
indicate problems elsewhere.
In /etc/conf.d/net, I have the line
dhcpcd_eth0="-t 5"
and in /etc/conf.d/wireless I have
dhcpcd_private="-t 5"
where "private" is my wireless network's ESSID; fix as applicable. (For
other networks I tend to just connect manually as for me that is a rare
occurance.)
