[Nix-dev] postfix fork fix

[Marc Weber]

Trouble:
initctl status shows postfix has stopped even when it's still running.
Patching postfix-script to not fork solves this issue.
Because I'm already running upstart-0.5 I'd like to paste the patch here
which might work for upstart-0.3 as well ?
Maybe someone wants to verify that the job still works?

Sincerly Marc Weber
