To test it on a regular system, you might install it, then run something like:
sudo rainbow-easy gaming /bin/bash sudo rainbow-easy banking /usr/bin/firefox -no-remote sudo rainbow-easy av /usr/bin/mplayer ~/some/movie
These examples will drop you into an isolated bash session, firefox session, or mplayer session in which you can play.
NB: If you want to isolate more complicated software, then you're going to use the low-level rainbow-run interface used by rainbow-easy. Here are some examples to help you get started:
Launch mplayer with a fresh nested Xephyr X server. sudo rainbow-run -v -v -v -s /var/spool/rainbow/2 -u $USER -c "`pwd`" -f 0 -f 1 -f 2 -E "DISPLAY=:0" -o audio -a /usr/bin/rainbow-xify -o xephyr -o network -- /usr/bin/mplayer ~/some/movie Launch bash in a previously generated container. sudo rainbow-run -v -v -v -s /var/spool/rainbow/2 -u $USER -f 0 -f 1 -f 2 -i secrets -r 10000 -- /bin/bash
Obviously, please contribute more automated tests, helpers, and bug reports!
