Title:
  /var/log/maas/rsyslog has incorrect permission

Status in “maas” package in Ubuntu:
  Fix Released
Status in “maas” source package in Trusty:
  In Progress

Bug description:
  [SRU justification]
  This fix is required to allow maas to log rsyslog events

  [Impact]
  Without this fix, no d-i log from MAAS can be written

  [Fix]
  Change the post install script code that sets permissions in /var/log/maas
  directory

  [Test Case]

  1. create pristine Ubuntu 14.04 LTS box 
  2. sudo apt-get update && sudo apt-get install maas 

  Actual result: 
  /var/log/maas/rsyslog/ is owned by maas:maas and not writable by syslog user. No log will be written. 
  $ ll /var/log/maas/rsyslog/ 
  drwxr-xr-x 2 maas maas 4096 Jul 16 06:26 ./ 

  Expected result: 
  /var/log/maas/rsyslog/ is writable by syslog user to store d-i log from MAAS nodes. 

  [Regression]
  None expected as only the rsyslog ownership is changed explicitely

  [Description of the problem]

  /var/log/maas/rsyslog/ is owned by maas:maas and has 755 permission
  after maas package installation. Therefore rsyslogd cannot write logs
  into the directory.

  How to reproduce:
   1. prepare pristine trusty box
   2. sudo apt-get install maas

  Expected result:
  /var/log/maas/rsyslog/ is owned by for example syslog:syslog.

  Actual result:
  $ ll /var/log/maas/rsyslog/
  drwxr-xr-x 2 maas maas 4096 Jul 22 01:13 ./

  Workaround:

  $ sudo chown -R syslog:syslog /var/log/maas/rsyslog

  It seems that 3 packages are trying to set owner related /var/log/maas/*.
