# When doing a build in a container, "apt-get update" happens twice,

|
# which can be a very significant overhead for incremental builds.

|
# And it's unnecessary, because if any of the prerequisites do change,
|
|
# the right thing to do is to rebuild the container image. Rather
|
|
# than suppressing the "apt-get update" commands explicitly, we clear
|
|
# out sources.list so that 'apt-get update' doesn't do anything.
