The port could be improved by adding support for pselect(2). Other than that, this port has a few MINIX-specific changes: - we undefine IN_IFF_ flags to stop dhcpcd from thinking that we have operating system support for link-local IPv4 address management; - we work around one crash bug that seems triggered by using dhcpcd on some but not all interfaces; - we add "noalias" to the default dhcpcd.conf(5) configuration file.
