Re: systemd-homed: home_on_a_stick
Yep, I like.
Much is why I use layered cows and vm's. Being ignorant and smart, I've hit many of these questions in designing what I have.
Inherited trust is something I've harped on elsewhere, and why do system things rely on home, and a user experience relies on things outside home...So much to fix in this 'superior' linux world.
In one setup I've played with, a usbkey containing the user is not only the /home but also a second layer cow to a read only image provided by the server, and also the luks hardware key for accessing that base image. Clumsy, I just brought the virtual whole system image along for the ride. And of course, nothing to do with laptops, more plugging into a 'terminal' with a system-on-a-stick without having the whole system on the stick. More narrowly focused I suppose...At least the usb-stick plugged in eleswhere is gobbly-gook unless you know what it is.
