[Nix-dev] Did services become pure?

[Manuel Pages]

Hmm, indeed that helped.

I made a directory called /public_services, allowed everyone to read from
it and moved my config there.
Rebuild worked. Now I'm confused with why doesn't postfix work (permission
denied on master.lock) and
what am I doing wrong there.

If anybody has a working postfix installation on NixOS, please share.
