[PKG-Openstack-devel] Bug#774788: Bug#774788: neutron-metadata-agent overwrites config on update

Hi Thomas

Well the commit
http://anonscm.debian.org/cgit/openstack/neutron.git/commit/?id=5c17e246c7e1ed00a7f58ba1be98ab0185d25b81

mentioned does definitly not solve the bug.

no I don't have better idea. Actually the question was more for me to
check my understanding of you're fix.

Another issue: I realized, that the old debconf values are still present
after upgrade. Do we not need to delete them ?
(I do not know package policy well  enough to have a qualified opinien
about that, but it would make sense to remove them I think.)

So I did some upgrade testing on my testing system (fresh install of
jessie, install neutron-metadata-agent, upgrade to you're new version.
Everything with
export DEBIAN_FRONTEND=noninteractive;
set.

The lines in the pkgos_write_admin_creds() function
in the neutron-metadata-agent.postinst script are guilty for the
troubles (as far as I see).

In 489 line you lookup the port in the config file. This one is
correctly taken. The protocol is switched to http hardcoded, as far as I
understand the code. And the hostname is taken from debconf value,
without respecting the value in the config file.

I currently not able to imagine where it reads the config file. (Sorry
;(). Especially I cannot understand why it does eg not change the region
which seems to me like equivalent configured.

So at the moment im sort of blocked for further investigation.

Cheers
