Windows Subsystem for Linux finally out of Beta

Microsoft has announced that the full version of Windows Subsystem for Linux (WSL) will roll out with Windows 10 Fall Creators Update (FCU). Windows Subsystem for Linux (WSL) is now out of beta and will become a fully supported Windows feature. Early adopters on the Windows Insider program will notice that WSL is no longer marked as a beta feature as of Insider build 16251.

This will be great news for those who’ve held-back from employing WSL as a mainline toolset: You’ll now be able to leverage WSL as a day-to-day developer toolset, and become ever more productive when building, testing, deploying and managing your apps and systems on Windows 10.

Caveat Emptor

  • Run Linux Command-line tools for development and (basic) administration.
  • Share and access files on the Windows filesystem from within Linux.
  • Invoke Windows processes from Linux, e.g.
    ~$ cd /mnt/c/temp/ && echo “Hello” > hello.txt && notepad.exe hello.txt.
  • Invoke Linux processes from Windows command-line, e.g.:
    C:\> bash -c “fortune | cowsay”

NOT supported:

  • Linux distro’s running atop WSL are for interactive user scenarios, NOT for running production workloads on Apache/nginx/MySQL/MongoDB/etc.
  • Linux files are NOT accessible from Windows (we’re working to improve this scenario over time).
  • NO current plans to support X/GUI apps, desktops, servers, etc. at this time.

According to the Microsoft, they support the WSL infrastructure and tooling and on the other hand, Distro-publishers are responsible for their distro internals.
