Description:
On Linux, the hostname can be set via this file if available, precluding
the need for a `hostname` binary.

How to repeat:
remove hostname and try to install mysql

mysql_install_db is deprecated as of MySQL 5.7.6, and with 5.5 and 5.6 having
come a fair bit along in their lifecycle, we are limiting the amount of
change in these versions. Thus closing this.
