     * MCR-Beta: <code> Hello! ODROID!
  - MCR-Beta -   </code>
+== Implementation ==
+The ODROIDs are now using [[https://www.armbian.com/odroid-c2/|Armbian]]'s [[https://redirect.armbian.com/region/EU/odroidc2/Focal_current_xfce|Focal (Fossa) XFCE release]] with an older version (early 2020 release) of the U-Boot bootloader flashed with the [[https://archlinuxarm.org/platforms/armv8/amlogic/odroid-c2|ArchLinuxARM]] [[https://web.archive.org/web/20210216103531/https://archlinuxarm.org/packages/aarch64/uboot-odroid-c2-mainline/files/sd_fusing.sh|sd_fusing.sh]] tool.
+This older bootloader version is flashed instead of using the one that is on the Armbian image, because at the time of installation, the version distributed on Armbian's ISO images is a more recent, broken version. (doesn't boot without a serial adapter connected, Ethernet doesn't work.
+Then:
+  * an ''odroid'' user and ''autom8'' user are created
+  * the ''autom8'' user gets the ssh key added
+  * the ''sudoers'' shutdown commands get added to the '/etc/sudoders' file
+  * a file to autostart XFCE, with the ''odroid'' user is added (lightdm)
+  * Add the Barrier SSL key to the Barrier's TrustedServers.txt
+  * add files to the ''odroid'' user's autostart (XFCE) directory:
+     * Start Firefox Kiosk mode with the corresponding URL
+     * Kill the xfce4 panel/menu bar because otherwise it shows up over the firefox fullscreen until the window is clicked on
+     * Start Barrier in client mode that automatically connects to the server (config) with SSL, or in server mode with SSL (config)
