Comment 1 for bug 1208865

Percona Server 5.1 and 5.6 are also affected:

[openxs@chief ~]$ cd /tmp/Percona-Server-5.1.72-rel14.10
[openxs@chief Percona-Server-5.1.72-rel14.10]$ grep -- --pid-file support-files/mysql.server.sh
      --pid-file=*) server_pid_file=`echo "$arg" | sed -e 's/^[^=]*=//'` ;;
      --pid-file=*) pid_file=`echo "$arg" | sed -e 's/^[^=]*=//'` ;;
        --pid-file="$pid_file" >/dev/null 2>&1 &
      $bindir/mysqld_safe --datadir=$datadir --pid-file=$server_pid_file $other_args >/dev/null 2>&1 &
[openxs@chief Percona-Server-5.1.72-rel14.10]$ grep -- --pid_file support-files/mysql.server.sh

[openxs@chief Percona-Server-5.6.14-rel62.0]$ grep -- --pid_file support-files/mysql.server.sh
[openxs@chief Percona-Server-5.6.14-rel62.0]$ grep -- --pid-file support-files/mysql.server.sh
      --pid-file=*) mysqld_pid_file_path=`echo "$arg" | sed -e 's/^[^=]*=//'` ;;
      $bindir/mysqld_safe --datadir="$datadir" --pid-file="$mysqld_pid_file_path" $other_args >/dev/null 2>&1 &

This is what we see in current cluster code (with the fix, I assume):
