Essentialy, this patch adds systemd.debug as an alias for
systemd.log_level=debug systemd.log_target=console. But it doesn't
really fix anything, just moves the initial problem to a different set
of options. This isn't useful. In addition, it is reasonable to use
"debug" to turn on verbose mode for the kernel + init combo, since in
practice this is what people need to diagnose boot problems.
