All three accept this configuration via /etc/network/interfaces, which 
is why I listed them.  They all use the same format, which is why I was 
suggesting they be used in place of dhcp3-client

Exactly.  This line would work for dhcpcd, pump, and udhcpc.  However, 
dhcp3-client does not, and this is the default dhcp client for ubuntu.

dhcpcd allows for a fair amount of configuration as well (which is what 
I use.)  If you use the resolvconf package, you can also manipulate what 
name servers you use.

I think you may have missed the point of my post.  Thank you for the 
information about requesting a hostname, but I was asking if there will 
be a gui means of doing a hostname request during dhcp.

The network configuration applet already modifies (or results in 
modification of) /etc/network/interfaces, and I was suggesting/asking 
that an alternative to dhcp3-client be used, as the other clients work 
with /etc/network/interfaces for hostname request.  I would assume that 
all that would be required is a simple change to the network 
configuration applet, to add the "hostname <yourhostnamehere>" line to 

Perhaps the debian configuration scripts could be changed so that 
dhcp3-client accepts additional configuration via 
/etc/network/interfaces as well?  I will poke into that.

Thank you for this wonderful distribution.
