Anything which can be used to manipulate, modify, or install a Debian,
Fedora, or Suse iso will also work with an Ubuntu-Sugar-Remix.  If not
it is a bug.

By way of background, ISOs evolved as a means of moving information on
and off of a CD in a single step.  When one burns a movie they are
generally coping the entire contents of a CD.  The key feature of an
ISO is the wide availability of authoring tools to work with them.
see http://en.wikipedia.org/wiki/ISO_image

ISOs have been around for several years and are well support by third
party tools.  IMG files have been used as backup files for since the
1970's.  dd, one of the common img manipulation tools, stands for Data
Dump.  dd make take the contents of partition and make a raw dump into
a file using the 'archive format.'  The dump can then be move around
and restored as need.

Early versions of Ubuntu Netbook Remix were distributed as img files
which users would copy onto USB sticks.  Recent versions of UNR have
move back to using ISO files as a distribution method for two reasons:
The ecosystem of tools to manipulate ISOs is larger and more widely
understood and casper (see earlier email) the ISO bootloader was quite
mature.

Ubuntu Sugar Remix Live will _not_ be a viable product until the funky
loopback mounted, Read Only, SquashFS is dealt with.  My stand, at
least for the 10.04 release, is that USR should be used and
distributed using stand Ubuntu and Ubuntu-Netbook-Remix tools and
procedures.  This way we can isolate 'Sugar' bug and deal with and
push system level bug to Ubuntu.
