+## sudo mysql_install_db
+Installing MariaDB/MySQL system tables in '/var/lib/mysql' ...
+OK
+
+To start mysqld at boot time you have to copy
+support-files/mysql.server to the right place for your system
+
+
+PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !
+To do so, start the server, then issue the following commands:
+
+'/usr/bin/mysqladmin' -u root password 'new-password'
+'/usr/bin/mysqladmin' -u root -h localhost password 'new-password'
+
+Alternatively you can run:
+'/usr/bin/mysql_secure_installation'
+
+which will also give you the option of removing the test
+databases and anonymous user created by default.  This is
+strongly recommended for production servers.
+
+See the MariaDB Knowledgebase at http://mariadb.com/kb or the
+MySQL manual for more instructions.
+
+You can start the MariaDB daemon with:
+cd '/usr' ; /usr/bin/mysqld_safe --datadir='/var/lib/mysql'
+
+You can test the MariaDB daemon with mysql-test-run.pl
+cd '/usr/mysql-test' ; perl mysql-test-run.pl
+
+Please report any problems at http://mariadb.org/jira

+NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
+      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
+
+In order to log into MariaDB to secure it, we'll need the current
+password for the root user.  If you've just installed MariaDB, and
+you haven't set the root password yet, the password will be blank,
+so you should just press enter here.
+
+Enter current password for root (enter for none):
+OK, successfully used password, moving on...
+
+Setting the root password ensures that nobody can log into the MariaDB
+root user without the proper authorisation.
+
+Set root password? [Y/n] Y
+New password:
+Re-enter new password:
+Password updated successfully!
+Reloading privilege tables..
+ ... Success!
+
+
+By default, a MariaDB installation has an anonymous user, allowing anyone
+to log into MariaDB without having to have a user account created for
+them.  This is intended only for testing, and to make the installation
+go a bit smoother.  You should remove them before moving into a
+production environment.
+
+Remove anonymous users? [Y/n] Y
+ ... Success!
+
+Normally, root should only be allowed to connect from 'localhost'.  This
+ensures that someone cannot guess at the root password from the network.
+
+Disallow root login remotely? [Y/n] Y
+ ... Success!
+
+By default, MariaDB comes with a database named 'test' that anyone can
+access.  This is also intended only for testing, and should be removed
+before moving into a production environment.
+
+Remove test database and access to it? [Y/n] Y
+ - Dropping test database...
+ ... Success!
+ - Removing privileges on test database...
+ ... Success!
+
+Reloading the privilege tables will ensure that all changes made so far
+will take effect immediately.
+
+Reload privilege tables now? [Y/n] Y
+ ... Success!
+
+Cleaning up...
+
+All done!  If you've completed all of the above steps, your MariaDB
+installation should now be secure.
+
+Thanks for using MariaDB!

+## Mounting SD card in Virtual Box VM
+
+********************************************************************************************************************
+Answer for Windows 7 users
+
+    Get the DeviceID of your SD card reader.
+
+    You'll need a card in the drive, mounted by windows.
+
+    Enter this command
+
+    wmic diskdrive list brief
+
+    It should look something like this:
+
+    C:\Users\Sandy Scott>wmic diskdrive list brief
+    Caption                      DeviceID            Model                        Partitions  Size
+    WDC WD7500BPKT-75PK4T0       \\.\PHYSICALDRIVE0  WDC WD7500BPKT-75PK4T0       3           750153761280
+    O2Micro SD SCSI Disk Device  \\.\PHYSICALDRIVE1  O2Micro SD SCSI Disk Device  1           3964584960
+
+    The last device is the SD card reader, so the DeviceID is \\.\PHYSICALDRIVE1
+
+    Create the link file to the SD card
+
+    Open a command windows as Administrator
+
+    "C:\Program Files\Oracle\VirtualBox\VBoxManage" internalcommands createrawvmdk -filename "%USERPROFILE%/Desktop/sdcard.vmdk" -rawdisk "\\.\PHYSICALDRIVE1"
+
+    This assumes the default installation path - change it if you need to. (Ensure quotes are around the rawdisk argument.)
+
+    The .vmdk file is a link to the SD card, you can put it anywhere on your host system, but this command just puts it on your desktop for convenience.
+
+    Follow steps 4-6 in JinnKo's answer, the only minor tweak is that you need to start VirtualBox as an Administrator
+
+        Next we attach the raw disk to a guest VM within the VirtualBox UI
+            Ensure the guest VM is not running.
+            Ensure VirtualBox is not running
+            Start VirtualBox by right-clicking on it and choosing "Run as administrator"
+            Open the settings area for the guest VM
+            Click on "Storage" in the toolbar
+            Next to the controller click on the icon to "Add Hard Disk"
+            Select "Choose existing disk"
+            Navigate to the /path/to/file.vmdk you used in step 3 and select it
+            You should now be returned to the Storage tab and see your file.vmdk in the list.
+        Start the VM
+        Depending on whether you have a GUI or not the SD card may or may not automatically mount. If you need to mount is manually it is simply exposed as another standard block device, so on my guest this was exposed as /dev/sdb.
