I recently had a play around with Ubuntu on Windows which is available in the recently released Windows 10 anniversary update.
For the uninitiated, Ubuntu on Windows is a command line environment running the server version of Ubuntu 14.04 LTS. It runs on top of a compatibility layer called Windows subsystem for Linux (WSL).
It functions similarly to the Wine tool for running Windows apps in Linux by providing binary compatibility for Linux apps. This is in contrast to the existing Cygwin tool, which uses linux apps compiled to work on Windows.
Currently, the tool is the beta stage of development and only supports Ubuntu 14.04.
Installation was a breeze. You need to enable development mode in windows first. WSL can then be installed by selecting this in the ‘Turn windows features on or off’ dialogue.
After installation, you are provided with a shortcut to launch a bash prompt. You currently need to set up a separate Linux user account, your Windows account doesn’t currently get imported. To avoid issues with network access, it is currently necessary to launch bash with Windows administrator privileges.
Ubuntu on Windows is targeted towards developers, web-developers in particular. I was able to install a number of packages from
apt-get without any issues, including Apache and MySQL. Note: Any background processes such as Apache will only run whilst there is a bash prompt open.
I did encounter a few issues, however. WSL currently lacks support for inotify. This is important for anyone using a development server such as
jekyll serve since inotify is required to listen for code & content changes and auto-reload them.
The integration with Windows could be improved. The entire Windows filesystem can be accessed from
/mnt/c/. However, accessing the Ubuntu filesystem from Windows is not as obvious. It is possible to access the home directories under
C:\Users\USERNAME\AppData\Local\lxss\home, although this is undocumented.
It seems that symlinks to the Windows filesystem don’t currently behave correctly (attempting to change directory inside a symlinked directory had no effect for me). You may want to do this to provide a shortcut to your Windows profile directory.
Overall, I think this is a useful tool and is certainly much quicker and easier to setup than a full virtual machine. However, for now I will continue to use a virtual machine running Ubuntu due to the current limitations.
