cwd in script is expanded to real path for symlinks

[azatoth]

When using for example shipit for deployment, it deploys into a releases/DATETIME dir and generates a symlink at current; When forever-service is executed in the currentdir, cwd is expaned into the releases/DATETIME and thus having the realpath encoded in the init script, resulting in having to delete and regenerate the scripts for each deployment.

Might be possible to change process.cwd into process.env.PWD though it's possibly platform dependent.
