RE: Bootable CD



	Hi,
	I have a question about the Red Hat 7.1 installation CD.
	The Red Hat installation disk has a GUI application that runs to
install it. In some point of the installation this programs ask to the user
to put the Red Hat disk 2, how is it possible if there is a file in the disk
1 mounted in the loop device? If you see the mtab file in the /etc you will
see:
	/tmp/loop    /mnt/runtime      ext2  ro 0 0 
	What is this file in loop? Is the file /RedHat/base/stage2.img
mounted there? It has the same content of the /mnt/runtime.
	How it is possible to change the CDs with this file mounted?

	Thanks,

Since... you don't.

That file is loaded to memory and gunzipped somewhere in the process, then
mounted as a RAM-disc.

Again: don't run it directly from CD, but run it from a RAMdisk
instead. You will need a fair amount of RAM to install an X server in a
RAM-disk, though.
