Makes sense. I actually hadn't realized that the Guix test suite (those
run with 'check' rather than 'check-system') were also derivations until
you mentioned it. It seems like looking at the implementation there
would give me a better idea of how to structure my tests.

I like that idea. There's a 'system-qemu-image/shared-store-script', but
no 'system-qemu-image-script', so I'll have to take what I did for my
test suite experiments and turn it into something proper.

'container' in the sense of 'guix environment' containers?
