You (or somebody else doing the rewrite) should make sure, that we
can easily follow later changes by upstream (here: Ubuntu). Maybe
you or the Debian package maintainer can talk to the Ubuntu people,
if they have plans for the future of the file.

Btw, an easy thing to change would be to replace Ubuntu with
&supplier; etc. and to define the entity in the header as
<!ENTITY supplier "Debian GNU/Linux"> etc. For other parts of the
document, it's more than that, of course.
