-Compressed cpio images
-----------------------
-
-Recent kernels have support for populating a ramdisk from a compressed cpio
-archive, on such systems, the creation of a ramdisk image doesn't need to
-involve special block devices or loopbacks, you merely create a directory on
-disk with the desired initrd content, cd to that directory, and run (as an
-example):
-
-find . | cpio --quiet -c -o | gzip -9 -n > /boot/imagefile.img
-
-Examining the contents of an existing image file is just as simple:
-
-mkdir /tmp/imagefile
-cd /tmp/imagefile
-gzip -cd /boot/imagefile.img | cpio -imd --quiet
