1. run file initrd.img first. That will tell you what type of file it
2. Most likely, you will need to uncompress it. Use zcat instead of
gunzip. The uncompressed file will be loopback mountable one.
Note: if you modify the mounted image file, you may have some fun
getting it to reclose. Unless there is some space left in the filesystem
created for it, you can't add anything. When you recompress it, you will
most likely need to use the max compression flag (--best) again with
zcat (or do a rename on the final file).
