Subject: [PATCH 1/2] cloud-setup: fix terminating in the middle of
|
|
reconfiguring the system
|
|
|
|
Once we start reconfiguring the system, we need to finish on all
|
|
interfaces. Otherwise, we might reconfigure some interfaces, abort
|
|
and leave the network broken. When that happens, a subsequent run
|
|
might also be unable to recover, because we are unable to reach the
|
|
HTTP meta data service.

Subject: [PATCH 2/2] cloud-setup: clear error variable in
|
|
nmcs_device_reapply()
|
|
|
|
This is rather bad, because if we reach the "goto again" case,
|
|
the error variable is not cleared. Subsequently passing the
|
|
error location to nm_device_reapply_finish() will trigger a glib
|
|
warning.
