/etc/mysql/mysql.conf.d/ not included in /etc/mysql/my.conf

[Antonello Alonzi]

On every Debian installation I see that /etc/mysql/mysql.conf.d/ directory isn't included into /etc/mysql/my.cnf

Why does the installation procedure create this folder if it is not included? This often causes confusion. To whom and how should this omission be reported?

thank you
