You can also create special files like fifos, unix sockets, and device files. To do this:. Linux permissions are added as additional metadata to the file. Once the file or folder has metadata, Windows and Linux permissions will not remain in lock-step with each other.

It was appropriately assigned msbob and metadatagroup for the owner and group bits, as expected. The umask used in this example will disable execution rights for files by default, which allows you to be more explicit in setting execution permissions on a file-by-file basis.

By default, WSL will set the uid and gid to the default user with drives that are auto-mounted during instance start. What do you think about the latest changes to DrvFs? Drop us a comment below or tweet at us! Comments are closed. Thank you for your text Craig.

I probably have to read it a few more times before I really understand it completely. Still this was the missing piece of the puzzle that would allow me to use wsl in my daily development. Remounting my drive with metadata made it work. Now I am able to downloads repos from git on the windows side…may sell my mpb now. Anyone got metadata working when mounting SMB samba mapped drives?

I too am trying to use chown to change the owner of a file Network drive mounts would simplify accessing the source data.

I checked the file Properties, and under the Detail tab I saw that the owner of the 2 files is different:.

After the first time, you can use git to talk to your hosting provider without needing to re-authenticate. It will just access the token in the Windows Credential Manager. Now any git operation you perform within your WSL distribution will use the credential manager.
