// SAFETY: We have allowed an override for the case where the current_exe() has
// been replaced or removed. By default the server will fail to restart if the
// binary has been replaced (i.e. by cargo); this is for security purposes.
// Command::exec() used to panic in that case.
//
// We can (and do) prevent that panic by checking the result of current_exe()
// prior to committing to restart, returning an error to the user without any
// unexpected shutdown. In a nutshell that is the execuse for this unsafety.
// Nevertheless, we still want a way to override the restart prevention (i.e.
// admin server restart --force).
