     rump.dhcpclient - simple dhcp client for rump kernels

     rump.dhcpclient ifname

     The rump.dhcpclient utility is a very simple DHCP client which can be
     used to apply networking configuration on one interface in a rump kernel.
     Unlike full DHCP clients, rump.dhcpclient does not store leases or renew
     expired leases.  The reason for this is the typical transient nature of a
     rump kernel.  Additionally, rump.dhcpclient does not save DNS resolver

     After having succesfully configured networking, rump.dhcpclient prints
     out the networking configuration and lease time and exits.

     Since rump.dhcpclient uses bpf(4) to send and receive raw network
     packets, the server must include support for bpf and vfs (for opening
     /dev/bpf).  Otherwise, the following diagnostic message is printed:

           rump.dhcpclient: bpf: Function not implemented

     rump_server(1), bpf(4)

     There is no easy way to release a lease.
