Description of problem:

Using openstack-packstack-2013.2.1-0.29.dev956.fc20.noarch:

When trying to install RDO on Fedora 20 via "packstack --allinone", the install fails with:

  ERROR : Error appeared during Puppet run: 172.16.0.4_mysql.pp
  Error: Could not start Service[mysqld]: Execution of '/sbin/service mariadb start' returned 1: 
  You will find full trace in log /var/tmp/packstack/20140210-191647-DfRatq/manifests/172.16.0.4_mysql.pp.log

  Feb 10 19:18:17 lars-f20-0 systemd[1]: mariadb.service: main process exited, code=exited, status=1/FAILURE

This is because the log file is owned by root:

  # ls -ld /var/log/mariadb/
  drwxr-x---. 2 mysql mysql 4096 Feb 10 19:18 /var/log/mariadb/
  # ls -l /var/log/mariadb/mariadb.log 
  -rw-r--r--. 1 root root 0 Feb 10 19:18 /var/log/mariadb/mariadb.log

Fixing the permissions on that file allows mariadb to start up
correctly.

  # chown mysql:mysql /var/log/mariadb/mariadb.log
  # service mariadb start
  # service mariadb status
  Redirecting to /bin/systemctl status  mariadb.service

Hmm, this may actually be an selinux issue:

# audit2allow -a
#============= mysqld_safe_t ==============
allow mysqld_safe_t var_log_t:lnk_file { read getattr };
