[Nix-dev] etc postfix subdir

[Kevin Quick]

I ran into the a problem trying to specify a file in a subdirectory of
/etc in my configuration.nix.

This works (with or without quotations):

   environment.env."postfix_vmailbox".text="foo";

However, if I try to specify this:

   environment.env.postfix/vmailbox.text="foo";

I get an "unexpected PATH" error, and if I add quotes:

   environment.env."postfix/vmailbox".text="foo";

Then I get the following error (services.postfix.enable=true):

building path(s) `/nix/store/drb8pwps60bcb8a1hsakv6qlqkikin2k-etc'
duplicate entry postfix -> /var/postfix/conf
mismatched duplicate entry  <-> /var/postfix/conf
builder for `/nix/store/mni4ljfsmmnx939wkyhb9aq3z4nb7b15-etc.drv' failed with exit code 1
cannot build derivation `/nix/store/6s4zh3waqnkg4s2nlr6y8bndyh1wqvbl-nixos-0.2pre4466_aaffb21-76a5e89.drv': 1 dependencies couldn't be built

I can use the first form, but the documentation at
http://hydra.nixos.org/build/4519492/download/1/nixos/manual.html (what
the nixos.org web page referenced) implies that the second
form should be possible, whereas the current github version of etc.nix
suggests the third.
