Subject: [PATCH] manager: when reexecuting try to connect to bus only when
|
|
|
923a60 |
dbus.service is around (#6773)
|
|
|
923a60 |
|
|
|
923a60 |
Trying to connect otherwise is pointless, because if socket isn't around
|
|
|
923a60 |
we won't connect. However, when dbus.socket is present we attempt to
|
|
|
923a60 |
connect. That attempt can't succeed because we are then supposed
|
|
|
923a60 |
to activate dbus.service as a response to connection from
|
|
|
923a60 |
us. This results in deadlock.
|
|
|

Fixes #6303
