# It's not recommended to modify this file in-place, because it will be
# overwritten during package upgrades.  If you want to customize, the
# best way is to:
#
# root> systemctl edit mariadb.service
#
# Then add additonal directives under a section (probably [Service]).
#
# For more info about custom unit files, see systemd.unit(5) or
# 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 MariaDB's open-files-limit to 10000,
# you need to increase systemd's LimitNOFILE setting, use the contents below:
#
#	[Service]
#	LimitNOFILE=10000
