So I released rawlink on opam and hdhcp should work now.

I had started to convert the code to mirage and I have some questions.

How exactly should the distribution be ? Should I release a package in opam that exports a "dhcp server module" ? Should I include something like a unikernel config.ml skeleton and friends ? Should it be included inside an existing mirage library ?

My idea so far was to release hdhcp as a library, having a Dhcp_server module, and another package with a mirage usage of this module as a functor. Basically it needs to be specialized on how to send/receive packets and read/write to disk.

I'm up for suggestions.
