It would basically be a config option that would say "getopt support for
udhcpd" or somesuch. If you didn't compile that in, udhcpd would always
background. If you did compile that in, you could add a command line
option telling it to stay in the foreground. Additional command line
options could be added later that would add functionality to udhcpd as a
general purpose tool, rather than a tool strictly for small, embedded
systems.
