Yes, just ignore the fact that these are VLANS, that part is
invisible to the dhcp server. All you need to do is configure a relay
agent in every LAN or VLAN - and of course define it in the server
config.
It is slightly more involved if you directly connect your server to
the VLANs via a trunk port. Then you need to configure VLAN support
on the server and define all the interfaces.
Secondary question of my own ...
I've just set up a Debian Etch box doing VLAN trunking to a switch
(for a multi-tennant gateway). DHCP appears to work fine on all the
virtual interfaces, are there any 'gotchas' I should be aware of ?
