> that are not Linux, but serviced by the Windows kernel's POSIX layer under WSL1.

that's not how that works.

wsl is a Linux kernel running under a hypervisor integrated with windows.

Wsl2 is how you say. WSL1 is a Linux syscall reimplementation in the NT kernel space.

I see and TIL.

Still said syscall reimplementation was not based off the old and long gone NT posix personality (just sayin' so I save face...)

If you examine the wiki, you will find that the POSIX layer of Windows is the first implementation.

I had known for some time that VAX/VMS was strikingly similar to Windows NT, but I learned a few days ago that the failed Mica project introduced a POSIX interface.

You're describing WSL2, but the post you quoted explicitly said WSL1.

But is WSL1 supported by the POSIX layer? I don't think so. I think it uses some of the mechanisms built for the POSIX layer but I think it is a separate "personality".

See my post to a peer; this comes from the DEC Mica project, the cancelation of which directly led to Windows NT.

Windows was designed in part as a UNIX kernel.
