Are you sure this is actually needed? The
BUSYBOX_INSTALL_LOGGING_SCRIPT and BUSYBOX_INSTALL_WATCHDOG_SCRIPT are
used as follows:

define BUSYBOX_INSTALL_INIT_SYSV
        $(BUSYBOX_INSTALL_MDEV_SCRIPT)
        $(BUSYBOX_INSTALL_LOGGING_SCRIPT)
        $(BUSYBOX_INSTALL_WATCHDOG_SCRIPT)
endef

So they are already only triggered for a sysv or busybox init.
Therefore, I've marked the patch as Rejected in patchwork. If we
misunderstood something, please let us know.

Thanks!

Thomas
