    Description

      The container's launch script sets up environment variables, symlinks etc.

      If there is any failure when setting up the basic context ( before the actual user's process is launched ), nothing is captured by the NM. This makes it impossible to diagnose the reason for the failure.

      To reproduce, set an env var where the value contains characters that throw syntax errors in bash.
