installation of mysql5.7 for centos 7 -using rpm/yum - missing mysql.server script

Upon installation of percona 5.7 for Centos OS 7, I did not see the script /usr/share/percona-server/mysql.start.
For the percona 5.6 installation, the script is there.

I also see less files in /usr/share for 5.7 than for the 5.6 installation.

Is this a bug or do we need to upgrade a toolkit, or create some manual script?
