I appreciate Patrick is focusing on Qubes so its not a request for him per se. I have several low spec notebooks which I have managed to get Whonix working on but the performance is understandably painfully slow. I would like to build a lean cut-down version of Whonix to run on these notebooks so that all they offer me is Tor Browser + wget + vi as that is all I require of them. So a little like the low spec Chromebooks you find for ~150 USD which simply throw you into a browser and that is all you get. I would appreciate some pointers on how to make a secure implementation. To my mind I need to build a cut-down Debian Jessie system for each VirtualBox VM (I am happy to use KVM if that is preferred). Then download the Whonix source from GitHub and presumably there is documentation on how to install the source?
What I am missing without having done further research is the mechanism of applying the Whonix source to my custom OS build so that it functions like the standard VB download. Of course I appreciate that the download is an export of a prebuilt appliance and I am building a new VM, that is a small matter.
Any links to any existing useful posts on how to achieve this task would be appreciated.
As an aside, I wish to extend this principle to building a Whonix bare metal Gateway using a RPi or a low spec notebook. So basically the cut-down Gateway I build should be customisable to run on bare metal instead of within a VM. Then I can connect another notebook which just runs a cut-down version of Whonix Workstation either on bare metal or a VB or KVM VM. If I run the Workstation in a VM, does anyone have any advise on how to set the n/w parameters so the Workstation can see the Gateway running on the RPi ? I mean when both are on same m/c and belong to the Whonix n/w there is no issue, but now lets say I connect the Workstation notebook to the Gateway RPi or notebook via Ethernet cable, then presumably the Ethernet interface on the RPi will be a different network than the WiFi INTERNET connection feeding the bare metal Whonix Gateway? So the question is how to bridge them if that is the correct term.
Thanks in advance for any advise.
