Hey Robert,

There is no plug to read from /etc on purpose. The goal is your snap to
be relocatable and not relying on anything system-wide, so that it can
run in different context. That's why you need to find a way to embedded
this file and looking for local assets.

If you want to change some env vars, you can create a shell wrapper that
you point your snap into. The shell will then executed your real binary,
once it has settled your environment properly.
Cheers,
Didier
