[bootsup]

another container based approach is what barry kauler of puppy fame is doing with https://easyos.org/.

I haven't used BSD, but I think jails are another solution in this space.

I used Qubes pretty heavily in school. The Windows 10 template was great for running STATA etc, and the way Qubes handles copy paste and file transfer were pretty great.

What I didnt like was having to restart qubes when updating software, and general complexity. I will go back to Qubes or something like it when I go back to school, though, as it is simpler to manage than multiboot or multiple computers.
