Indeed, but which kernel?!?

I'm running Microsoft's Linux "kernel". WSL1 that is, where they re-implemented everything :)

Don't you find it a bit disappointing that in WSL2 they're basically walking back the Linux-userland-on-NT-kernel architecture? I found this way of doing it fairly impressive - I wonder whether they will get good FS integration and performance with WSL2.

I find it impressive that they didn't give in to the fallacy of sunk costs, and switched tech to something better. WSL was impressive, but WSL2 is in my experience better, and it's pretty cool that they can start Linux in a VM so rapidly, and give it access to as much of the host memory as it wants.

WSL1 itself is a recycling of Arcadia... with the UI bits and binder removed.

(Android compatibility subsystem for Windows 10 Mobile)

that's a good point, but it hinges on FS performance becoming good enough in WSL2 I think.

That's the point of WSL2 — FS perf was quite bad in the first version (although I still use it regularly!).

Well, that and getting the rest of the missing syscalls in... But FS perf is what I'm most excited about.

Hurd?
