Bug#1004333: deb-systemd-helper does not recognize purged package

[Marc Haber]

retitle -1 please consider more debugging in state file handling
severity -1 minor
thanks

Turns out that it was an issue in the test system.

Please, however, consider adding a bit more debugging and error
processing. Here is the patch that I used to debug this. This is clearly
not suitable for the release code, but I think you get the idea

+    }
+    open(my $fh, '>>', $statefile) or die "cannot open: $!";
     close($fh);
 }

Retitling and resetting severity.

Greetings
