What if... someone made a Plan 9 that could run Linux apps?
I was writing about MicroVMs the other day:

It made me wonder... if you can have a Linux VM that starts in milliseconds, could you create one for a vaguely Unix-like but non-Unix OS, such as Plan 9, so that it could run Linux binaries on this non-Linux-like OS?
ISTM you'd need two or three things, all of which either exist or are doable.
