systemd-bsod [OPTIONS...]
systemd-bsod.service is used to display a blue screen which contains a message relating to a boot failure, including a QR code which can be scanned to get helpful information about the failure.
The following options are understood by systemd-bsod:
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
-c, --continuous
When specified, systemd-bsod waits continuously for changes in the journal if it doesnt find any emergency messages on the initial attempt.
Added in version 255.
On success (displaying the journal message successfully), 0 is returned, a non-zero failure code otherwise.
