As I wrote: There is NO file mounted as a loop device while you're running
RedHat's (or Debian's) installer. The fact that I told you to mount it
using the loop device does not mean it's the only way to mount it.

The installer does it the following way:

It loads it into RAM. Once it's into RAM, it's got the filesystem as a
RAM-disk and can actually access it from RAM. That is to say, without
CD-ROM. See?


Have a look at initrd for details on how to do this.
