Package: release-notes
Severity: normal

The upgrade instructions should include a section on system watchdog daemons
(eg. micro-evtd). Following the current instructions means the daemon will be
stopped in the middle of the upgrade when its replacement is unpacked, meaning
the watchdog will be tripped a short while after.

I've added the following to the "Prepare a safe environment for the
upgrade" section of the wheezy release notes:

+<para arch="armel">
+  Users of the watchdog daemon provided by the <systemitem
+    role="package">micro-evtd</systemitem> package should stop the daemon and
+  disable the watchdog timer before the upgrade, to avoid a spurious reboot in
+  the middle of the upgrade process:
+  <screen>
+# service micro-evtd stop
+# /usr/sbin/microapl -a system_set_watchdog off</screen>
+</para>
+

Cheers,
Julien
