QEMU (Short QUick EMulator ) provides way of running software for a number of different hardware platforms. For Linux Operating Systems it is able to boot directly from a kernel and inital ramdisk file. This is the option we will use so as to bypass the additional complication of compiling a boot loader and formating physical media with these files. The following wikepedia entry gives additional information about QEMU: http://http://en.wikipedia.org/wiki/QEMU
qemu-system-arm -kernel ${CLFS}/boot/clfskernel-3.10.13 \
-initrd ${CLFS}/build/initramfs -M vexpress-a9 -redir tcp:5555::80 -m 128 -serial stdio -append "rdinit=/sbin/init console=tty1"
When the boot is complete, the embedded ELFS system is ready for use!
