Fix one liner curl-bash combo

[toliver]

The problem with premature exit is due to the way we run the script with the one liner.

With

curl -L www.aaa.com | bash

the contents of the file are connected to the std_in of bash. That becomes a problem when we run commands that capture the std_in like apt-get install.

The suggested way to run it is:

bash <(curl -L www.aaa.com)

Then it's run like a script file.
