[Bug 2009230] Re: AppArmor denials for rsyslog

[Georgia Garcia]

** Also affects: gce-compute-image-packages (Ubuntu)
   Importance: Undecided
       Status: New

** Description changed:

  The AppArmor profile for rsyslog, which had been disabled on previous
  Ubuntu versions, was enabled in lunar.
  
  The package google-compute-engine added a config file to rsyslog which
  requires rw access to /dev/console
  
  google:ubuntu-23.04-64 /root# cat /etc/rsyslog.d/90-google.conf
  # Google Compute Engine default console logging.
  #
  # daemon: logging from Google provided daemons.
  # kern: logging information in case of an unexpected crash during boot.
  #
  daemon,kern.* /dev/console
  
  google:ubuntu-23.04-64 /root# apt-file search /etc/rsyslog.d/90-google.conf
  google-compute-engine: /etc/rsyslog.d/90-google.conf
  
  So in gce cloud images, we are getting the following denials:
  
  [ 1500.302082] audit: type=1400 audit(1677876883.728:495):
  apparmor="DENIED" operation="open" class="file" profile="rsyslogd"

  requested_mask="ac" denied_mask="ac" fsuid=101 ouid=0
  
+ To fix it, we just need to add

- To fix it, we just need to add 
-   /dev/console rw,
