The proposal to merge ~mgerdts/cloud-init:lp1667735 into cloud-init:master has been updated.
Commit message changed to: DataSourceSmartOS: fix hang when metadata service is down If the metadata service in the host is down while a guest that uses DataSourceSmartOS is booting, the request from the guest falls into the bit bucket. When the metadata service is eventually started, the guest has no awareness of this and does not resend the request. This results in cloud-init hanging forever with a guest reboot as the only recovery option. This fix updates the metadata protocol to implement the initialization phase, just as is implemented by mdata-get and related utilities. The initialization phase includes draining all pending data from the serial port, writing an empty command and getting an expected error message in reply. If the initialization phase times out, it is retried every five seconds. Each timeout results in a warning message: "Timeout while initializing metadata client. Is the host metadata service running?" By default, warning messages are logged to the console, thus the reason for a hung boot is readily apparent.
