          This option specifies when the dhcpcd service will fork to background.
          If set to "background", dhcpcd will fork to background immediately.
          If set to "ipv4" or "ipv6", dhcpcd will wait for the corresponding IP
          address to be assigned. If set to "any", dhcpcd will wait for any type
          (IPv4 or IPv6) to be assigned. If set to "both", dhcpcd will wait for
          both an IPv4 and an IPv6 address before forking.
          The option "if-carrier-up" is equivalent to "any" if either ethernet
          is plugged nor WiFi is powered, and to "background" otherwise.
