// Package sd_daemon provides functions for writing "new-style"
// daemons.
//
// The daemon(7) manual page has historically documented the very long
// list of things that a daemon must do at start-up to be a
// well-behaved SysV daemon. Modern service managers allow daemons to
// be much simpler; modern versions of the daemon(7) page on GNU/Linux
// systems also describe "new-style" daemons. Though many of the
// mechanisms described there and implemented here originated with
// Systemd, they are all very simple mechanisms which can easily be
// implemented with a variety of service managers.
//
// [daemon(7)]: https://www.freedesktop.org/software/systemd/man/daemon.html
package sd_daemon
import "errors"
// ErrDisabled is the error returned when the service manager does not
// want/support a mechanism; or when that mechanism has been disabled
// for this process by setting unsetEnv=true when calling one of these
// functions.
var ErrDisabled = errors.New("Mechanism Disabled")
