Eelco Dolstra 2a4417d637 * make-etc / activate-configuration: allow /etc files to be installed
as regular files instead of symlinks to the store.
* Sudo configuration, enabled through security.sudo.enable (on by
  default).  The contents of the sudoers file is specified in
  security.sudo.configFile.  The default sudoers file allows members
  of the new "wheel" group to run any command.
