We probably should ask for the nagiosadmin password via debconf, as
the nagios 1 packages do. If somebody wants to implement this, please
feel free.

I'd like to have a decision about that rather soon.

After working on nagios2 for a day, I feel it is terribly wrong to be
in nagios subdirectories. We belong in nagios2 subdirectories.

Only if you insist on "nagios", the data will stay there. I am very
strongly in favor of moving to nagios2 directories.

The large commit I did half an hour ago makes the .deb build cleanly,
and has the daemon running after installing the packages. At build
time, upstream's sample config is patched to reflect Debian changes
(in the future, failure in patching will break package build so that
we notice changes in upstream's sample config that might affect us),
and a minimal config file only checking localhost is installed.
Upstream's samples to into /usr/share/doc/nagios2-common/examples.

debian/rules has two new targets, unpack-configs and pack-configs.
unpack-configs will merge our diffs and upstream's samples to
debian-configs/ for package build or local changes, and pack-configs
will re-generate the debian-diffs for the cfg files after doing local
changes. This has been mercilessly ripped from exim4, thanks to
Andreas Metzler for working on this.

What still needs to be done is listed on the wiki page, and after
these things are done (which are still pending your "go ahead", which
I hope to receive after working so much on the package in the last few
days) the packages are ready to go to experimental.

For me, they are "good enough" to install on the first test system and
to try backports to sarge.

Greetings
Marc
