I'm trying to assign addresses via DHCP for a number of different
networks (using ip-helper and option 82 on the switches). It's going to
be tough for me to come up with a predefined list of what leases belong
to what port, but it's definitely something I should be able to figure
out when the lease is coming in. There's also the fact that the config
file would end up being quite large if I pregenerate it for every
possible combination.

I'm not 100% certain, but the way I read the man page, the script is
triggered after the dnsmasq event occurs, so you can pass some custom
behavior to a script after dnsmasq has managed the lease. However, it
sounds like you want to customize dnsmasq behavior and insert your own
algorithm for allocating IP addresses? Just out of curiosity, why?
You can specify quite a complex set of allocation rules using tags and
more, why would you need to have anything other than that?

I'm trying to set up a DHCP server so that on any request for a
new lease I can execute a script and have the script return an IP
address (and other information).
Is this something that is currently possible with dnsmasq? From
reading the man page, I can't tell if I will get this behaviour
with --dhcp-script --leasefile-ro.
Basically, it would be impossible for me to specify all the
possible DHCP leases at startup, but when a lease request is
received I would be able to determine what IP to assign.
