- Update of rootfile not required
- Renamed build_mountpoint patch
- Changelog
    3.10
	When the user executes "machinectl stop", systemd sends SIGRTMIN+4 to PID 1
	 in the container, and expects that to initiate a graceful shutdown
	 (power-off). SysV init now catches this signal and initiates a shutdown
	 (shutdown -hP now).
	Fix issue in bootlogd which could cause the service to enter an endless loop
	 (and use too much CPU) when it is able to open a device for writing, but not
	 actually able to write to it. This resulted in bootlogd closing and
	 re-opening the device over and over. Now bootlogd should simply fail
	 gracefully when it cannot write to an open file/device.
	Fix formatting in shutdown.8 manual page. Cleaned up whitespace and special
	 characters.
    3.09
	On Linux distributions which use the musl C library (instead of glibc) we can now
	 build properly. Specifically, the hddown helper program now builds on musl C
	 systems.
	The reboot command is now able to pass messages to the underlying firmware on
	 Linux systems during a reboot. This allows the admin to pass information to the
	 underlying firmware to, for example, ask the system to boot from another
	 partition. Should be helpful on Raspberry Pi systems.
	 The reboot command can pass a message to the firmware when using the "-m"
	 command line flag.
	This release also improves the Makefile's clean directive.
