Treat squashfs just like the iso mount as squashfs is a readonly file
system just like the iso is. You have to copy the files to a  read/write
area to edit them.  The -w short for -o rw gives no joy to prove out
where you are having trouble.  You will still get the readonly file
system message.
~ mount -o loop -t squashfs -w /mnt/iso/images/install.img /mnt/stage
