+# here is where to define which server start.
+#> Additional parameters to be passed to mysqld at startup may be added here,
+#> these one will override the ones in "my.cnf".
+#
+# Below are described some suggested parameters to use
+# The parameters not recognized will be passed through to the mysqld daemon
+#
+# Parameter : description
+# ----------------+-----------------------------------------------------------
+# nice : integer [-20 .. 19 ] default 0
+# : change the priority of the server -20 (high) to 19 (low)
+# : see "man nice 1" for description
+# ----------------+-----------------------------------------------------------
+# mycnf : string [full path to my.cnf]
+# : specify the path to my.cnf file to be used
+# ----------------+-----------------------------------------------------------
+# TODO chroot : string [path to chroot directory]
+# : Tell the script that the server will be run in a chrooted
+# : environment.
+# : You may want to "mount -obind" a shared directory for the
+# : socket (usually /var/lib/run) or to instruct every client
+# : that connect to localhost (thus using sock connection)
+# : (will NOT be passed to the MySQL server)
+# ----------------+-----------------------------------------------------------
+#
+# Additional parameters
+# Parameter : description
+# ----------------+-----------------------------------------------------------
+# server-id : integer [1 .. 255]
+# : Uniquely identifies the server instance in the community
+# : of replication partners.
+# ----------------+-----------------------------------------------------------
+# port : integer [1025 .. 65535] default 3306
+# : Port number to use for connection.
+# : loose any meaning if skip-networking is set.
+# ----------------+-----------------------------------------------------------
+# skip-networking : NULL, Don't allow connection with TCP/IP.
+# log-bin : string [name of the binlog files]
+# : Log update queries in binary format. Optional (but
+# : strongly recommended to avoid replication problems if
+# : server's hostname changes) argument should be the chosen
+# : location for the binary log files.
+# ----------------+-----------------------------------------------------------
+#
+# start a default server with default options:
+# need symlinks (try emerge --config =dev-db/mysql-[version])
+#
+#mysql_slot_0=()
+#
+# start MySQL 7.5.x reniced, chrooted and overriding some start parameters
+#
+#mysql_slot_705=(
+# "nice=-5"
+# "chroot=/chroot/mysql-705"
+# "server-id=123"
+# "log-bin="myhost"
+# "port=3307"
+#)
+# start another server, same version, different my.cnf
+#
+#mysql_slot_705_1=(
+# "mycnf=/home/test/my.cnf"
+# "server-id=124"
+#)
+# To avoid starting a server just comment it's definition
+# To avoid confusion mysql init script MUST found at least one definition
+#> here or it will rant (no default start)
+# Last but not least, spaces are NOT allowed inside the parameters
