Thanks [~vvasudev]. Latest patch looks good, I am +1 on the Windows side

approach and Linux side.

> 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.
