Да, похоже я был слишком категоричен. Дельтами обновляется далеко не
всё. Вот что об этом сказано в Debian Release Notes, Chapter 5:

"5.1.5 Slower updates of APT package index files

By default, the etch version of apt uses a new way to update APT
package index files (when you run aptitude update) which downloads
differences files (instead of the full package index file) called
pdiff. This new feature should use less bandwidth and be faster for
most systems. Unfortunately, it can also have the opposite effect of
making the updates slower on systems with fast network connections (or
a very nearby mirror) which are infrequently updated, as it might take
more time for the system to merge the differences files than to
download a full package index. It is possible to disable this feature
by adding Acquire::Pdiffs "false"; to the /etc/apt/apt.conf
configuration file.

This change mostly affects users of the unstable and testing branch of
Debian GNU/Linux, due to the changing nature of these archives. Users
of etch will notice this feature mainly when updating their package
status for the security archive."
