+#
+# Main Differences: 
+#   - Start stop and reload is handled by systemd, removed
+#   - update handled by pacman, removed
+#   - changed from init script to "minecraftctl" command.
+#   - uses /etc/conf.d/minecraftd for variables
+#
+# Changes:
+#
+#   Changed running screen to work as root, broke it out into mc_docommand
+#   Commented echo commands for successful execution to not spam the log.
