> 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.
