For the first case, you should add the following to your init function

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
