# It's not recommended to modify this file in-place, because it will be

# containing
|
|

# .include /lib/systemd/system/mariadb.service

# ...make your changes here...

# http://fedoraproject.org/wiki/Systemd#How_do_I_customize_a_unit_file.2F_add_a_custom_unit_file.3F
|
|

# For example, if you want to increase mysql's open-files-limit to 10000,
|

# you need to increase systemd's LimitNOFILE setting, so create a file named
