# intermediate dummy, needed because AF_PACKET-sockets gets the packet

Self isolating binaries

This is a play proposal for a new wrapper around go build that would build your binary but wrap it in code that would prepare isolation around your binary on run.

A concept of this is in https://github.com/jfrazelle/binctr, in that it takes a docker image and embeds the contents into a final binary so you have a self-contained binary.

The binctr example is unnessesarily heavy for go binaries because all you need is a completely static binary.
