> Sometimes when a container fails, it can be pretty hard to figure out why it 
> failed.
> My proposal is that if a container fails, we collect information about the 
> container local dir and dump it into the container log dir. Ideally, I'd like 
> to tar up the directory entirely, but I'm not sure of the security and space 
> implications of such a approach. At the very least, we can list all the files 
> in the container local dir, and dump the contents of launch_container.sh(into 
> the container log dir).
> When log aggregation occurs, all this information will automatically get 
> collected and make debugging such failures much easier.
