Indeed. I've added this paragraph to the top of "Possible issues during or
after upgrade" section in the Release Notes:

  <p>Sometimes it's necessary to enable APT::Force-LoopBreak option in APT
  to be able to temporarily remove an essential package due to a
  Conflicts/Pre-Depends loop. <prgn/apt-get/ will alert you of this and
  abort the upgrade. You can work around that by adding something like
  <tt>APT::Force-LoopBreak "true";</tt> in <file>/etc/apt/apt.conf</file>
  or by specifying <tt>-o APT::Force-LoopBreak=1</tt> option on
  <prgn/apt-get/ command line.

(if anything's wrong with the above _please_ contact me before today's
dinstall run)
