Yes, but not all modules.
Unfortunately, OER2Go.org is not totally ready yet. After some modules (KA-Lite, Kolibri, and any of the Wikipedia modules), you’ll have to SSH into the device and run a script that is included in the module called finish_install.sh which you must run.
Alternatively, if you have all the modules you want unzipped on an external harddrive. You can SSH into RACHEL and rsync the modules from the external harddrive to the internal one. During this process, the finish_install.sh script should run automatically.
