>
> 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.
