[ale] backup DHCP

[David Corbin]

I've had some recent problems with my home network situation.  I strive very 
hard to keep it 'reliable' for my wife, as she depend on it for various 
things.  Today, one problem that showed up was that she lost her network 
connection.  This was because of dhcp 'problems'.

It would be easy enough for me to run 2 DHCP servers, each with different 
blocks of addresses.  But surely there is a way to run a "backup DHCP server" 
that uses the same configuration.

Any pointers?
