This made me curious enough to install Inferno and give it a go. Since I know next to nothing about its architecture consider this a cursory finding.
It appears ‘os’ executes the commands given to it on the host system as the user who started the Inferno emulator. Running Chromium through the ‘os’ command leads to the process showing up normally and belonging to the user who executed the Inferno emulator. So it doesn’t seem like any sandboxing is provided by running applications on the host machine in this way. - Nic
