Subject: [PATCH] systemd: try harder to bind to notify socket
|
|
|
|
Without the socket open we are going to crash and burn. If for
|
|
whatever reason we fail during deserialization we will fail when
|
|
trying to open the socket. In this case it is better to unlink the old
|
|
socket and maybe lose some messages, than to continue without the
|
|
notification socket.
|
|
|
|
Of course this situation should not happen, but we should handle
|
|
it as gracefully as possible anyway.
