Bug Description

When upgrading percona-server-server-5.1 "percona-server-server-5.1.postinst" runs /bin/bash /usr/bin/mysql_install_db --rpm 2>&1 | $ERR_LOGGER to ensure system tables exist.
I may create bin-log files if they were enabled in my.cnf before.
If there is no "user=mysql" option in [mysqld] section, the bin-logs are owned by root.

However when MySQL is started by mysql.server (e.g. /etc/init.d/mysql) group [mysql.server] is processed where "user=mysql" may be specified.

Root owner of the log files prevents mysqld to start. It can't read the last log due to "permission denied" error.

By the way, chown -R mysql $mysql_statedir is not processed when $mysql_statedir is a symlink
