Windows - Support 'bash for Windows'

[bobsummerwill]

At the Microsoft //BUILD conference a few days ago, Microsoft unveiled "Bash for Windows", where they have added a subsystem to the OS which supports a full set of Linux syscalls. They are hosting a vanilla Ubuntu 14.04 (Trusty) userspace from Canonical on top of that.

I think that we should just be able to use these instructions and it should "just work".

This might pull in a lot of additional dependencies. Do we really want that?

[bobsummerwill]

It won't. It's literally the Ubuntu Trusty userland. Same binaries.

Just trying our Trusty instructions in this environment which should be the same.

I gave it a whirl last night. I'll just keep looking at this for fun. It shouldn't need any changes on our side. More a question of reporting any problems to Microsoft.

Sure, it will pull in the trusty userland. Admittedly, we also explicitly provide all the dependencies for the native build...

I've already found an issue with Bash on Linux on Windows; scary as todo el infierno for me. Ok... I go in to either Powershell, type 'bash' and go from there, or just go into the Bash on Ubuntu on Windows program itself & go from there. When I'm in, however I choose to get there, I've tried out the calls the demo guy does from the Channel 9 video, the one w/ Rich Turner & Russ Alexander demo'ing.

So I get to the part where Russ.... I think he's the one doing demo. But he is gonna show a piece of code in the vi editor, and I thought 'oooh.... how cool if I could go in & try to get at my VS code and throw it up here!!!!!!'.... so I (without quotes) 'cd /mnt/c', and I'm mounted; then I 'ls' and I get this error: 'ls: cannot access Documents and Settings: Input/output error', and then 2 other 'Permission Denied' errors. I'm more concerned about the Documents and Settings error... and obviously, not just because I want to throw something up to friggin' vi editor..... ugh!!!!!!!

I just turned on the Insider Preview builds on this machine last night, it's a Gateway NE5 laptop, Pentium 2.4 Gig, Windows 10 Home, Version 1511, Preview Build 143.16.1000.

Am I worrying for nothing, since this effectively IS a preview build? Everything really works great, I can access the Documents and Settings here in Windows, I can get to them via Powershell; I should note that I got an error the first time I installed Bash... it was 0x and a bunch of other numbers. Looked on forums and someone said you had to uncheck a box to do with Legacy Mode in Powershell/Cmd - disabled in one and turned off for all. :) And then I was able to get Bash on Ubuntu on Windows up and running. :D Sorry for being so damn long winded.

Hope somebody can help!!!!!

There are lots of issues in Bash-for-Windows at the moment, @adampoewilson, it seems.
It is in its very early stages.

Just report whatever you see at https://github.com/Microsoft/BashOnWindows/issues. They're been pretty responsive. I imagine they will be doing updates every month or so.

As of June 9th, we can build but not run eth on Bash-for-Windows.

See #567.
