path fixing patches for zfs and spl package
removed local-fs.target to speedup booting (not needed - /storage is already mounted by initramfs)
fixed dependencies, configure options and makeinstall_init, enabled systemd service
added default /etc/hostid in initramfs and populating it from kernel cmdline, busybox is built with hostid cmd, added hostid=* kernel cmdline param, added hostid.service to populate the hostid from kernel cmdline (with fallback from /proc/sys/kernel/hostname)
added make_init() to have possibility to include out-of-kernel modules into initramfs
