Ahi, you are right, mon ami. Even if the disk seems to be "rw":
/mass/iso/master.iso on /mnt type iso9660 (rw,loop=/dev/loop0)
this not really the case, because I tried to save a file, without
success.
So, the iso9660 format cannot be dynamically changed. Surely, this is
not a Linux or Windows limitation, but, probabily, comes from the audio
(historic) nature of this format.
Not a big problem, really. You can always mount it and copy it in a
directory:
# cp -a /mnt/* /my/dir
After that, you can rebuild the master.iso with
# mkisofs -rJ -c boot/boot.cat -b boot/boot.img
-o master.iso /my/dir
As you see, the "-b" option tell to mkisofs where the El-Torito floppy-disk
(here boot.img) is.
As far muLinux "clone" is concerned, this is not really necessary, because
the script doesn't cancel the workspace (see WS). You can always add some
other material in the WS/master directory and finally re-create the
iso image. This is the solution that I suggest for You.
