systemd-bsod.service, systemd-bsod — Displays boot-time emergency log message in full screen
systemd-bsod.service
/usr/lib/systemd/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¶--version¶-c, --continuous¶When specified, systemd-bsod waits continuously for changes in the journal if it doesn't find any emergency messages on the initial attempt.
--tty=¶Specify the TTY to output to. By default systemd-bsod will
automatically find a free VT to display the message on. If this option is specified a TTY may be
selected explicitly. Use --tty=/dev/tty to direct output to the terminal the command
is invoked on.
On success (displaying the journal message successfully), 0 is returned, a non-zero failure code otherwise.
