There is a floating point multiplication done of a base image size
and an "overhead factor", which is currently rounded up to the next
integer. If the multiplication results in a whole number, the value
will still be a float. When this float is used to generate a shell
script, a buggy script is generated.
Fix this by always forcing to an integer.
