Ubuntu on Windows

So what OS you're going to get when you run an application under this? So if I run this:

    node -e 'console.log(require("os").type())'

What it's going to print?

Would depend entirely on how you installed node, I would imagine.

Whatever it prints on Ubuntu I expect. Obviously it's not going to return "Windows", or "UbuntuInWindows" else anything that makes that call that would break.

As WinLS is very much like branded Solaris Zones, here's what it looks like when you run `uname -a` in an (old, copypasta from the web) Linux branded zone:

    Linux centos 2.4.21 BrandZ fake linux i686 i686 i386 GNU/Linux

Depends if the node is a Windows executable or a Linux binary.

So if I install Node as a Linux binary. Can I access it in Windows "environment" too?

Does that mean I can do "apt-get install nginx" from their new "bash" terminal app? Does that then run under port 80 in Windows? Since no VM is involved.

I'm still a bit confused.

See this screenshot showing uname -a: https://1.bp.blogspot.com/-PTJrez4z0Jc/Vvr-VH5DQOI/AAAAAAAFH...

Seems less honest than the Linux env on FreeBSD, which at least puts FreeBSD in there for uname -a. Eg:

% uname -srm FreeBSD 10.3-RELEASE amd64 % /compat/linux/bin/bash bash-4.1$ /bin/uname -srm Linux 2.6.32 i686 bash-4.1$ /bin/uname -a Linux viserion 2.6.32 FreeBSD 10.3-RELEASE #0 4b75b72(releng/10.3): Fri Mar 25 19:14:5 i686 i686 i386 GNU/Linux bash-4.1$ cat /proc/cpuinfo | grep 'model name' | head -1 model name : Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz

I just see this as a headache for developers.

I don't want or need a Linux ABI, I just want to run a Linux container on Windows (if I have to use windows, which I would prefer not to do).

If node running on windows needs access to a database running on the Linux layer then what happens when things aren't working? They can't possibly make all programs interact in a seamless way.

I'm imagining frankenstein programs that are hacked together with code that only works on this frankenstein OS.

If you want a Linux container on Windows (which they do not seem to propose right away, but it seems a logical step), you need a Linux ABI.

>Does that then run under port 80 in Windows?

Yes, they demonstrated that localhost is the same localhost under both environments.

Looks like, if a posix system is detected at compile time, it will return whatever it gets from the `uname` system call in `sys/utsname.h`:

Microsoft probably hard-codes a response of "Linux" (or whatever would be normal for Ubuntu) for that call to prevent Ubuntu binaries from freaking out.
