[Maas-devel] New packaging branch to test

[Andres Rodriguez]

Hi Julian, 

So I have tested the package and so far seems working as expected. I
have yet to test a few things. 

Issues identified are:

1. dbconfig-common needs to handle the a database for the
maas-region-controller instead of maas. This has been uploaded to the
package in the PPA. 

https://launchpadlibrarian.net/117549060/maas_0.1%2Bbzr1085%
2Bdfsg-0ubuntu1%2Bppa0_0.1%2Bbzr1085%2Bdfsg-0ubuntu1%2Bppa1.diff.gz

The patch is here though. Please apply it.

2. maas-cluster-controller echo's a config file
"/etc/maas/maas_api.conf"
This means that when we remove the package this config file is left and
not removed. 2 ways to handle this.

2.1 Install the config file from the package itself (much preferred) so
that removes are handled automatically.
2.2. On maas-cluster-controller.postrm we need to remove the file on a
purge manually. (I prefer 2.1 because is less prone to errors. This
would mean however that the config file will need to be edited with, say
sed.)

3. Currently, the only file that is requiring manual intervention on
upgrade is maas_local_settings.py. If NO is selected, installation
fails. So we need to find a way to handle this automatically, to not
require user's interaction.

Hope this helps. I will continue testing, most likely tomorrow early
morning. 

Note that I have also added "-x" and random messages to the
postinst/postrm scripts to be able to debug this. I know it is annoying
but it really helps helping me debug.

Cheers.
