hashbangctl.conf can't be stored in shell-etc because it contains a secret.
Maybe this isn't that big of a deal because who cares about that file anyway, right?
But nonetheless, I'd like to see all admin-tools type stuff store all the secrets in a way that allows uses to have maximum visibility into /etc.
For many years, users on many *nix boxen have been able to read all the files in /etc that weren't explicitly verboten by permissions. With a little work, we might be able to get back to that.
