github issue

Problem

When multiple users try to user VSCode devcontainer on a remote server, some files are initialized in the /tmp path with the user ownership.
When a second user tries to user VSCode remote server, he's stuck on an ACCESS DENIED error in these folders.

Workaround

Each user shall create a folder with his username in /tmp and export in his .bashrc the variable TMPDIR=/tmp/$USER.
