Hi Hugo,

on HA cluster, important services are managed by heartbeat. Therefore, all runlevels for hiawatha are disabled by default.
Automatic update fails for both active and inactive HA servers and has to be performed manually.

PROBLEM: Update process stopped Hiawatha on active server, but didn't started it afterwards,
this has to be performed manually.

Errors were encountered while processing:
hiawatha_9.3_amd64.deb

PROBLEM: This is much worse, Hiawatha did't update at all just because it was not running!

SUGGESTED BEHAVIOR:
Hiawatha has to update, regardless of its status (started/stopped). After Update, it should come back to it's previous status,
no matter how the runlevels are set.

Hiawatha itself doesn't do anything with runlevels. So, it must be somewhere in the Debian init script. I have no time to look into this heartbeat thing, so please let me know what to change.

Unfortunately, my workload will be too high in the next 3-4 weeks. I'll look into it later, if it's not repaired by then by someone else.
