Hi Mélodie,

This is described at several places in the Ubuntu community wiki. Also I
have described it, even uploaded such compressed iso files


where there is even a Bento file. Do you remember?

- The main reason I made those compressed iso files was that some
computers wouldn't boot directly from the iso files via syslinux /
isolinux. But with the option forcepae that problem is solved.

- The problem with a script is that it must be maintained to fit new
versions of the software. Otherwise it can be convenient. A generic
script will not work for all iso files.

- The advantage with mkusb is that it will work in most cases. We need
hybrid iso files, and all current Ubuntu family iso files are hybrid iso
files (with the exception of Ubuntu 12.04 mini.iso).

Why do you want this? I think it is easy enough to re-use the pendrives
(install what you need for the moment). And there are several multiboot
systems available already.

Best regards
