I notice that a reconfigure of wpa_supplicant causes it to drop the
control directory and never recreate it. This happens both when the
reconfigure is initiated by SIGHUP or with "wpa_cli reconfigure".
(In the latter case, the directory is gone before wpa_cli completes
and so wpa_cli hangs.)

The issue does not really affect me: I thought of using reconfigure,
then found that reassociate is sufficient for my needs. Still, this
seems a bug that ought to be noted or fixed.


Issue also reported upstream:
