OK indeed it does. (However there seem to be some doubled messages, and
the verbosity overfills the file a bit. probably due to the kernel parameters.)

Well it is too bad the user needs to deposit in that directory instead
of doing some command...

Anyways surely mentioning this method in
/usr/share/doc/systemd/README.Debian.gz "Debugging
boot/shutdown problems" would be valuable.

Indeed it _seems_ nowadays everything one sees during boot (after the grub
countdown) does end up in journalctl and dmesg... so no more need for
bootlogd, etc.
