Slax IS perfect for this. Very interesting.

Would you enable or disable the persistent save? Nothing saves to the host computer, only the usr file on the usb stick
Pro - you can boot and go with your settings but if someone got a hold of it could be bad. I guess you encrypt the drive
Con - having to cold start each time with settings is a pain
I wouldn’t have persistent save on the device.
I’m booting from a URL, I am booting from WAN aka the internet. Suggest any persistent data should be encrypted and stored over the internet.
The USB has nothing except kernel init and boot loader firmware, 4.2mb in total.
You physically possess nothing.
No data not even an OS.
Ah I see. Very clever
