Install to CD/DVD or flash drive?

[kevinmcguire]

Is it possible to create a usable version of OpenEMS and Octave on a flash drive or CD/DVD disc which afterwards is not writable? If so, are there instructions?

My goal is to boot a machine into Ubuntu using a flash drive or CD/DVD (using the "Try Ubuntu" option), then run OpenEMS from another device, and save files to a third device. I only want the device with "my" files to be writable at any time.

Thanks!

To run software in/from a not writable folder (at least for a non root user) is pretty much the default??
I would not see why the openEMS install folder should be writable...
