With my OpenStack Debian package maintainer hat on...
TL;DR: Moving to a single configuration file is unimportant for me, what
I would like is configuration files that I can easily parse.
Longer version:
The issue hasn't been multiple configuration. I've dealt with that by
parsing the core_plugin value, and do what should be done in the init
script depending on that.
The main issue with current configuration files is that they are *not*
parser friendly. Eg, there stuff like:
# Example:
# directive = value
#directive=<None>
A script cannot make the difference between the first and the 2nd
instance of the directive, and it's like this all over the place in
Neutron configuration files. Something like this:
sed -i "s/[ \t#]*directive[ \t]*=.*/directive = newvalue/" \
/etc/neutron/neutron.conf
which I extensively use (well, it's a little bit more complicated as
what I do doesn't show in /proc: for security purposes, directives
values shouldn't show in a ps, but you got the point...).
Even worse, there's some huge example snippet which I had to delete (for
the same parseability reasons). These belong in the openstack-manuals,
or in the sphinx doc, *not* in a configuration files.
So for me, parseability should be addressed with top priority. I am
currently patching the neutron configuration files because of this, and
I have to constantly rebase my debian-specific patches, that's boring,
and error prone. I'd very much prefer generated configuration files like
for other projects instead (on a single or multiple configuration files:
I don't care since I have the logic already implemented...).
Cheers,
