Ok, thanks.

This needs to be written. How to enable the 1.x urls? Is there more to
do than answer "yes" to the debconf question? What happens when I say
"yes" with nagios 1.x still installed?

How are the configuration snippets activated? Do they need to be
linked manually from /etc/nagsos to /etc/apache[2]?

The HTML docs form a significant part of nagios2-common's size They
don't need to be present on every system running nagios2, but they
might be wanted on a personal workstation for reference without having
Nagios2 actually installed. I'd like to see them separated, but I
don't feel strongly about that.

Need to still verify that.

What is upstream's opinion about using later config.guess, config.sub
before nagios2 release?

Would be a possibility, but generally Debian discourages autoreconf at
package build time. I am also not an expert in autofoo, so I'd prefer
to convince upstream to use current versions of the tools.

Do you want me to get in touch with upstream?

We'd need to do that for the unstable upload.

I didn't do it. Another thing to be done before the unstable upload.

I think that /usr/share/nagios2 would be appropriate. We can always
move it back to /usr/bin should it show necessary to invoke that file
on a command line.

I'll investigate.

I should have documented my findings further.

I'd go for nagios2stats since the word play doesn't work with the 2
thrown in. I don't feel strongly about that, your decision.

I see. So we'll have to stay with the hard dependency :-(

So we'll need to investigate which ping command line the ping plugin
uses these days.

Yes, right. But that's stuff for unstable.

I know it in theory, but do not have any practice and am not familiar
with the caveats that do surely exist.

This, however, introduces an upload dependency between nagios2 and the
plugins packages. I'll need to think about that before uploading the
first nagios2 package.

Maybe it is time to migrate the plugins packages to svn then. Who else
is working on the plugins packages?
