Fixes upgrade 1.2.0 to 1.4.0 while the directories do not exist after upgrade to version 1.4.0. So FreeRDP can not access this folders with "daemon" user. So I obtained this parts from the guac-install.sh to make RDP work again on upgraded 1.4.0 Version.
# Fix for #196
mkdir -p /usr/sbin/.config/freerdp
chown daemon:daemon /usr/sbin/.config/freerdp
# Fix for #197
mkdir -p /var/guacamole
chown daemon:daemon /var/guacamole
