- You can't set get_gateway='none' as a kernel command line option; it's documented as supported, but it doesn't work and you get an onscreen complaint that the network configuration is not valid
- You can't netboot if your DHCP server doesn't supply a router option without supplying a gateway interactively
There's also a no_default_route option given by 'debconf dumpdb' on a part-booted machine. I've yet to find any documentation of this or any evidence that it has an effect (also, assuming 'default route' == 'gateway', using the synonym in one setting is unhelpful).
