This example was mounting
/dev/zero
as/dev/nulo
inside the container. Thenulo
name was intended to be a "made up / custom" name, but various readers thought it to be a typo for/dev/null
.This patch updates the example to use
/dev/foobar
as name, which should make it more clear that it's a custom name.
