I've heard there's interest in reproducible builds, since I've already worked on reproducible rust I've documented how to do that.

The reprotest command can be included in a CI system like travis (ping me if you need further instructions).

I just noticed I forgot to remove -fileordering. This can be enabled safely, assuming the system supports fuse and has disorderfs available.

That's very cool! I'll review this soon. In the mean time, @devrandom might have some comments or suggestions.

Would also be good to make that reproducible.
