// 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 preventation (i.e.
|
|
// admin server restart --force).
