Package: release-notes

The "hidepid" mount-options for /proc (as recommended by various
online hardening HOWTOs) work with Stretch but cause problems on
Buster, and are considered an unsupported configuration by systemd
upstream - see #819808, #892585, #897654.  So users should probably be
advised to disable hidepid before doing a dist-upgrade.

Proposed text for issues.dbk:

  <section id="hidepid-unsupported">
    <!-- stretch to buster-->
    <title>Hidepid mount options for procfs unsupported</title>
    <para>
      The hidepid mount options to <filename>/proc</filename> are known to cause
      problems with current versions of systemd, and are considered by systemd
      upstream to be an unsupported configuration. Users who have modified
      <filename>/etc/fstab</filename> to enable these options are advised to
      disable them before the upgrade, to ensure login sessions work on
      &releasename;. (A possible route to re-enabling them is outlined on the
      wiki's <ulink
      url="https://wiki.debian.org/Hardening#Mounting_.2Fproc_with_hidepid";>Hardening</ulink>
      page.)
    </para>
  </section>

I can't claim to have tested the advice on that Hardening link on a
modern laptop running GNOME-on-wayland with pulseaudio and udisks2 and
network-manager and so on, but if it's wrong, we should correct the
wiki rather than the pointer.
