If I'm not mistaken this is already covered in "4.1.4 Prepare a safe
environment for the upgrade":
http://www.debian.org/releases/etch/i386/release-notes/ch-upgrading.en.html#s-upgrade_preparations

Maybe the 'should' to be changed to a 'must' and a footnote could be
added describing this issue. Also, the section "4.1.2 Inform users in
advance" could be changed to describe that users running a X11 session
will not be able to work and all users in that situation should be
asked to log out from their X sessions (remote or local).

Javier

PD: Is there a way to make gdm/kdm block out users from login in
through an upgrade through the use of a banner text? If so, that could
be recommended too.
