units: add systemd-debug-shell.service If enabled, the service provides a root shell from an early boot. It also remains active late into shutdown. It is useful for debugging startup and shutdown problems. This is the unit referenced in http://freedesktop.org/wiki/Software/systemd/Debugging#early_debug_shell

ConditionPathExists={{DEBUGTTY}}
units: order sysinit.target, debug-shell.service after systemd-vconsole-setup Previous patch to add an implicit dependency effectively orders various getty services after systemd-vconsole-setup.service. But I think it's cleaner to also order the service before sysinit.target, like it was before 8125e8d38e3aa099c7dce8b0161997b8842aebdc. There might be units which don't do use TTYVHangup= but would like to have the console fully initialized. Also, add a manual ordering to debug-shell.service, because it has ImplicitDependencies=no. This might delay debug-shell.service a bit, but systemd-vconsole-setup.service has no dependencies and should be very quick, so this should not be noticable in practice. Without the ordering, the terminal might not have a key map loaded, making debug-shell.service hard to use.
