Delta rpms, relative to the latest distro release, are long overdue.
(And not only in the Mandriva world. Also for Mozilla, OpenOffice, etc.)
Note that for much commercial software, updates are normally delta.
Such updates are often erroneously called patches.
This may be partly a limitation of rpm packages, or more the programs
that install/update such packages. If so, it should be a priority to
correct this lack.
The latest 3 updates for Mozilla Seamonkey were for security, all in the
same month, and only a handful of the many thousands of contained files
were changed. But it required downloading almost 13 M instead of
probably less than 100 K. For a distribution containing thousands of
such packages, it is understandably worse.
However, the idea of update ISOs is good as well.
This could be facilitated by the option of downloading the latest update
for each package of the release not already present in the download
destination (and preferably removing outdated updates).
There is already an option for Rpmdrake to not erase downloaded packages.
(Unfortunately one must manually edit a configuration file to select it,
but that can easily be corrected.)
It also would be useful to have the option to change the download
With these changes, creating an update ISO would be only a matter of
copying the contents of the update directory to an ISO.
Of course, an utility to directly create an update ISO from the
repository would be useful, but the advantage of the above approach is
that a moderately limited bandwidth user could download updates as
produced (that is over an extended period), and produce complete update
ISOs for others at any time.
my 2 cents :)
