rty, probably something in my my.cnf is causing the large mem usage, i ran the tuning scripts, and decreased, then increased memory sizes, but I am pleased with the way it is running. Here is my my.cnf. Thanks again, for the great step by step install in post 1 here.

# This is for a system with little memory (32M - 64M) where MariaDB plays
# an important part, or systems up to 128M where MariaDB is used together with
# other programs (such as a web server)
#
# MariaDB programs look for option files in a set of
# locations which depend on the deployment platform.
# You can copy this option file to one of those
# locations. For information about these locations, do:
# 'my_print_defaults --help' and see what is printed under
# Default options are read from the following files in the given order:
# More information at: http://dev.mysql.com/doc/mysql/en/option-files.html
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
# the syntax is:
#
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
# where you replace <host>, <user>, <password> by quoted strings and
# <port> by the master's port number (3306 by default).
#
# Example:
#
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
# MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
# start replication for the first time (even unsuccessfully, for example
# if you mistyped the password in master-password and the slave fails to
# connect), the slave will create a master.info file, and any later
# change in this file to the variables' values below will be ignored and
# overridden by the content of the master.info file, unless you shutdown
# the slave server, delete master.info and restart the slaver server.
# For that reason, you may want to leave the lines below untouched
# (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id = 2
#
# The replication master for this slave - required
#master-host = <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user = <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password = <password>

That's strange. On my Pogoplug V2, idle mem usage of Mariadb is only around 17%. The original MySQL took around 25%.
$this->bbcode_second_pass_quote('tedm', '
')I think it's best now that it's running stable (uptime is at a record 16 days!) I will just run mysql when needed, which leaves quite a bit of free resources, and a snappy nginx/php, samba, and sshd server.
Yup, after all to start mysqld just simply take one line command "systemctl start mysqld".
