iscsi/iscsiroot.sh: do not trust iscsistart return value

	/lib/$LIB/liblsp.so => /lib/lib64/liblsp.so (0x00007faf00727000)

also unset LD_PRELOAD, so we get a clean environment
systemd/rootfs-generator.sh: exit 0
systemd/rootfs-generator.sh: ignore legacy root=/dev/nfs
systemd: add 71-seat.rules 73-seat-late.rules
