This package can do a deterministic build of a package inside a VM.
## Deterministic build inside a VM
This performs a build inside a VM, with deterministic inputs and outputs. If the build script takes care of all sources of non-determinism (mostly caused by timestamps), the result will always be the same. This allows multiple independent verifiers to sign a binary with the assurance that it really came from the source they reviewed.
Synopsis:
* Install prereqs:
sudo apt-get install python-vm-builder qemu-kvm
* This will create the base VM for use in further builds (requires sudo):
bin/make-base-vm
* This will build using a YAML description file (can be run as non-root):
bin/gbuild _package_-desc.yml
The resulting report will appear in result/_package_-res.yml
