  1. Support tools like fdisk and dd to directly accss physical and virtual drives

    Please add support tools like fdisk and dd to directly accss physical and virtual drives. Right now, running `fdisk -l` outputs "cannot open /proc/partitions" and doing something like `dd if=G: of=disk.img` outputs "dd: failed to open ‘G:’: No such file or directory". I do not see anything in /dev/ that seems to indicate anything is mapped to drives in Windows.

      • sudo npm install -g serverless

        What makes wsl so useful to me and many others is being able to do web/cloud based development stuff from within Windows. At the moment I've had good results with things like the AWS CLI for linux and many other things, but serverless is not playing ball:

        nickw@DESKTOP-OREBB4V:~
        $sudo npm install -g serverless
        /usr/bin/serverless -> /usr/lib/node_modules/serverless/bin/serverless
        /usr/bin/sls -> /usr/lib/node_modules/serverless/bin/serverless

        • LXC (cgroups?) support

          Linux Kernel provides a way of grouping processes into isolated environments. This is the basis of LXC and Docker. Adding these primitives to the WSL Kernel would help with building applications and packages in a clean environment (see: snapcraft cleanbuild, which uses LXD: https://snapcraft.io/docs/reference/snapcraft-command#cleanbuild) without cluttering our main Ubuntu installation with packages that are not needed for general use, but are needed to build a single package that one time (at band camp).

          • Add Wireless Device Support

            iwconfig and other wireless device tools cannot interact with wireless devices. While ifconfig, ip, etc network support has been added and displays the wireless devices (wifi0, wifi1, ...), iwconfig and other tools cannot detect wireless support. Considering the omnipresence of wifi, this makes the "Enable network connection enumeration" request feel technically fulfilled but practically half-done. Can we expect wifi support in the near future? Or are there work arounds involving the installation or compilation of particular tools?

            • Add camera support

              It would be great if the bash can connect to the cameras on the PC/laptop. I was trying to use ARtoolkit but it wouldn't run on bash because the camera is not connected to the bash.

              • Please enable WSL to run 32 bit ELF binaries

                It seems that executing 32bit ELF binaries results in "Exec format error" - guessing the kernel doesn't have 32 bit emulation support (compilation is fine, but precompiled binaries don't run). A vast number of legacy programs are still 32 bit, please add support if it won't completely destroy everything in the process - thanks!

                  • Support for running systemd

                    Not to replace the current WSL init, per se, but it would be very useful to be able to run "systemd --system --unit=foo.target" as a way to set up and manage sets of services/daemons required for particular development, etc., configurations.

                    • Unify Branding

                      Right now, the branding for this feature is kind of all over the place:

                      - Windows Subsystem for Linux
                      - Bash on Windows
                      - Bash on Ubuntu on Windows

                      I realize that WSL is probably, strictly speaking, a separate feature/team (I'm guessing), from BoUoW; and that BoW is probably the same thing as BoUoW, just shorter ... however, the fact that they are all used interchangeably in official blog posts and documentation can be quite confusing when a) searching for information, and b) when communicating about the feature to others.

                      I'm sure there are reasons for this, including internal team…

                        Now that we’re delivering multiple distros via the Windows Store, we’re beginning the transition the branding of this feature to just WSL from “Bash [on Ubuntu] on Windows”.

                        In the future, instead of running “Bash on Ubuntu on Windows”, you’ll just run Ubuntu or openSUSE, or SLES, or Fedora, etc. and they’ll run on WSL.

                        We’re updating our docs and will start to transition our messaging over the coming few months.

                      • vaapi / vdpau support for hardware video decode/encode acceleration

                        Command-line tools such as ffmpeg or gstreamer that deal with video can optionally use hardware acceleration for various codecs, depending on GPU support -- see https://trac.ffmpeg.org/wiki/Hardware/VAAPI

                        It would be great if the hardware acceleration for video already supported by Windows native drivers could be exposed via VAAPI and/or VDPAU interfaces to be used.

                          • Support gpg2 smartcard integration (yubikey)

                            Don't see a way at present to use a yubikey/smartcard inside WLS. Seems like this would require USB support in order to integrate directly. Only workaround at present is to SSH into WSL and forward the ssh key, which makes the ssh-agent available to WSL, but still not the gpg-agent.

                              • Filesystem slow compared with native Ubuntu system.

                                http://www.phoronix.com/scan.php?page=article&item=windows-10-lxcore&num=1

                                Lists some benchmarks across Ubuntu and this subsystem. It is very competitive with Native Ubuntu Linux, except when it comes to filesystem access.

                                Filesystem access is important for compilation, as well as the thousands of "watcher" js and ruby programs that constantly touch the filesystem, which are the stated target market.

                                So, find a way to speed that up. (I don't know how you are currently mounting the filesystem, so I can't offer any ideas, other than removes as many layers as possible to the filesystem.)

                                If you are using the ntfs systems in Linux, you might consider implementing…

                                • enable kernel header support, as well as linux-tools-3.4.0+

                                  Some features that require kernel support, such as openAFS and perf (and kernel level linux-tools in general), do not work due to lack of kernel support. Is that something we can expect to be implemented any time soon? Perhaps, not by implementing a Linux kernel, but by having Windows kernel work with Linux kernel headers?

                                  • Replace the titlebar colour into black. White titlebar is distracting to CLI contents.

                                    The current white titlebar (when not using the optional theme color) is really distracting and just looks out-of-place on CLI.

                                    I suggest that the console window should be like this: https://imgur.com/a/UQZS9

                                    This is Hyper, a 3rd-party terminal app. An example of modern looking CLI that I think Windows deserve to have out-of-the-box. It is clean and way more focused to the CLI itself rather than the GUI chrome.

                                    • Access symbolic links (created by WSL) in Windows

                                      Create a symbolic link (ln -s target_file link_name) in WSL. The sym link works correctly with WSL. While the link is visible in Windows Explorer, attempts to follow (or delete) the link in Windows result in an error that the file is not accessible by the system. Is this by design?

                                      • Linux like mouse click selection and copy/paste

                                        In *Nix systems we can drag select text. Alternatively double left-clicking will smartly select a word/path (etc) boundary. Clicking for the third time selects the entire line. In all instances above it will auto copy to the selection to the clipboard.

                                        Whilst we have some slightly better options with Quick edit and insert mode there's still some subtle differences than the experiences above.

                                        Can we more closely mimic this behaviour?

                                        • WSL: wayland/display manger support , may be easier or more efficient to implement then xorg

                                          I would rather see this then xorg it would likely be more efficient in the long run then trying to cobbled together some hacked up version of x
                                          wayland is closer to the kernel it would pair nicely with WSL
