Well actually I didn't close it because I Cc:'d the reply to the original
mail to debian-bugs-done (the one without the BUG# in the subject).

Of course you are right there. I was hesistant to change the script
because it is marked as a config file, and upon re-installation dpkg will
ask if you want to replace it which is dangerous. Anyway I've fixed
it now, and I will upload 2.61-3 asap. I assume Bruce will update the
base system to the most recent base packages regulary ?

While on the subject, I think that marking these startup scripts as
config files is wrong. The configuration should be in seperate files,
for example in /etc/sysconf  (or whatever).
