That /may/ happen at some time, but not now, so we need a solution that
supports the current mish-mash of /*/*bin directories.

How will you mount /usr if it needs a module? This is the sort of chicken
and egg situation that an initramfs can avoid, by making sure everything
the boot process needs is available.

Since someone has already asked about this off-list, the method is
described on sysrescd.org and involves a GRUB menu entry like

echo "Adding: System Rescue CD"
menuentry "System Rescue CD" {
   set sysresiso=/systemrescuecd-x86-2.5.1.iso
   loopback loop $sysresiso
   linux (loop)/isolinux/rescue64 rootpass=whatever setkmap=uk isoloop=$sysresiso
   initrd (loop)/isolinux/initram.igz
}
