[systemd-devel] [PATCH v2] use systemd.debug on the kernel command line, not "debug"

If the kernel is started with "debug", that's for the kernel to switch
into debug mode.  We should rely on a namespace for our options, like
everything else (with the exception of "quiet").  Some people want to
only debug the kernel, not systemd, and the opposite as well so make
everyone happy.
