Browse source 
Remove from default configuration options that are compiled in like
default paths and character set. On the other hand add few examples of
tweak options that might be handy.

# * Character sets
#
# MySQL/MariaDB default is Latin1, but in OpenWrt we rather default to the full
# utf8 4-byte character set. See also client.cnf
#
# Note: In OpenWrt until mariadb 10.2.19-2 the baked-in defaults were
# "DEFAULT_CHARSET=utf8" and "DEFAULT_COLLATION=utf8_general_ci". As MariaDB's
# utf8 (supports three bytes per character) is not really UTF-8 (which needs up
# to four bytes per character) this was changed. Now the baked in-defaults are
# the upstream defaults (Latin1), but in the default configuration (like in the
# file you are currently reading) utf8mb4 is set, which is real UTF-8.
#
# Of course you are free to change this, either here or in a configuration file
# of your own which is read after this .cnf file, see my.cnf in parent folder
# (files are read in alphabetical order).
