Alternative root systems (userlands) for WSL

It might be worth adding a few examples of third party projects that exchange the ubuntu root file system for other popular linux distributions. A notable example is ALWSL, which brings a custom archlinux userland. The project page is here. References are mostly news/blogs. Examples: HackerNews, IDG's Inforworld, Techworm. There's also loose list of other developers with their own distros (such as Fedora) that can be found in the BoW github issues. Alphaneuron (talk) 14:18, 30 September 2016 (UTC)[reply]

GNU vs Ubuntu

Why is there "Ubuntu binaries" and "Ubuntu user-mode", not "GNU user-mode"? Ubuntu is just a distribution. GNU is the userland and tools. 94.254.177.22 (talk) 15:07, 15 April 2016 (UTC)[reply]

Because they're running binaries direct from the Ubuntu distribution, not source code compiled to run on Windows Subsystem for Linux. The GNU project don't, as far as I know, distribute binaries, they just distribute source.

Furthermore, not all the programs in Ubuntu's userland come from the GNU project, so the userland is more than just GNU. Guy Harris (talk) 19:22, 15 April 2016 (UTC)[reply]

The irony of this "No it's GNU."/"No it's Ubuntu." argument is that neither is correct. Yesterday, Seth Jennings, a Senior Software Engineer at Red Hat, demonstrated Fedora binaries, taken from a Docker image, running on the subsystem. If there's a name for what binaries run here, it is Linux binaries, i.e. binaries that make Linux system calls to (what they expect to be) a Linux kernel. This is the name used by FreeBSD writers and Solaris/Illumos writers. It's also the name used in the Wikipedia lxrun article.

There's "what binaries can WSL run?" and there's "what binaries does Microsoft ship?" The answer to the former is probably "Linux binaries"; the answer to the latter is "Ubuntu binaries". Guy Harris (talk) 20:56, 18 April 2016 (UTC)[reply]

What it *probably* runs are "ELF 64-bit LSB executables". You folks need to read your Tannenbaum. — Preceding unsigned comment added by 131.215.115.31 (talk) 16:28, 20 October 2016 (UTC)[reply]

Executable AND LINKABLE format. Without GNU runtime system you can't do nothing. They have to prepare their subsystem to run different user space libraries. Filiprino (talk) 02:50, 28 June 2017 (UTC)[reply]

An introduction that explains why this is useful might be nice.

I.e., what was the business model? Who is the user? Why would this be their preferred solution? Without that, this seems like a strange hybrid of two divergent worlds. MrRedwood (talk) 22:24, 15 April 2016 (UTC)[reply]

I have added this: Microsoft envisages WSL as "primarily a tool for developers -- especially web developers and those who work on or with open source projects." -Lopifalko (talk) 15:57, 4 October 2016 (UTC)[reply]

MSDN references

I note that the article seems to be rated generally as 'Stub' and notice that there seems to be further material available for writers on the MSDN blogs, to extend the article.

WSL – Windows Command Line Tools For Developers‎

One of the most interesting things about the Windows Subsystem for Linux (WSL) is its ability to run unmodified Linux ELF64 binaries atop the Windows Kernel.

One of the most frequent questions we get about Bash/WSL is how WSL provides a Linux-compatible filesystem atop NTFS and how filesystem interop works.

Do not change Linux files using Windows apps and tools

I have to provide this guidance at least 2-3 times a day so instead I am publishing it here so everyone can find / link-to this guidance.

https://blogs.msdn.microsoft.com/commandline/2016/11/17/do-not-change-linux-files-using-windows-apps-and-tools/

A search on the MSDN Blogs for WSL (by search or, separately, by tag) yields many more usable source materials.

Happy editing!
