I believe the answer is no. There is a way to handle it (a script that 
the daemon will run), but the details are specific to the DHCP client 
you are using. The most common ones are pump, dhcpcd, and dhclient, and 
I don't know which of them Ubuntu uses (Debian-Sid offers all 3, plus a 
few others, and even there, I don't know which is most commonly used). 
See which daemon your system runs and check its man page for the 
specifics of its config rules.
