Hi Thomas!

I've just taken over maintainership of the nagvis package and wanted to
let you know, that your bug hasn't been forgoten.

I agree that ideally a simple apt-get install nagvis should result in a
working installation, but I'm not sure, if all of the issues can be
fixed.

Yes, ndoutils have to be activated.  This is documented in
/usr/share/doc/ndoutils-nagios3-mysql/README.Debian.  I fear there is
nothing I can do in the nagvis package, so I clone this bug report to
the ndoutils package, and well's dicsuss this issue seperatly.

Hmmm... Seems that the handling of the configuration was at one point
broken.  That's something I can try to fix (and which might be even get
included into a fix for the stable package; but I'll have to check that
first).

However, please also note, that these parts of nagvis have been changed
with recent upstream releases, so I hope in will work better with
future version of the nagvis package.

I'm sorry, but I fear that's something that can't be done.  While I
understand your motived, doing that would completly violate the Debian
policy, and the Debians package management system can't really handle
such changes, so even if I changed that file (ignore that in theory you
could run nagvis on a seperate box than your nagios installation), it
would be lost with the next upgrade of the nagios package shipping it.
So I fear that's something you'll have to do by hand.
