[Bug 1483923] Re: dpkg-divert breaks nginx installation

[Benjamin Bach]

@Thomas Ward
Firstly, a correction: 14.04 also has the issue, I was looking at the wrong file ( http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/nginx/trusty/view/head:/debian/nginx-core.postinst is correct )

Let me try to summarize the issue a little better:

You have a package, johnny-dep, and it depends on nginx
johnny-dep has `dpkg-divert /etc/nginx/nginx.conf` in its preinst script

When we install johnny-dep, nginx will also be installed. What happens
is this:

1) johnny-dep adds the diversion, now there is no file /etc/nginx/nginx.conf
2) nginx installs, but during its configuration it exits because there's no /etc/nginx/nginx.conf

--

Meanwhile, I found this work-around/solution:

I listed nginx in "Pre-Depends" in my debian/control, thus nginx will
run its postinst script before johnny-dep's preinst script is run.

If this is enough to consider this a non-bug, that's acceptable. Maybe I
disagree a little bit that nginx doesn't work conventionally with a
diversion of its configuration file, but on the other hand, it's not
very severe.
