This statement tells BitBake to issue an error instead of
trying to access the Internet.
This technique is useful if you want to ensure code builds
only from local sources.

This statement limits the build system to pulling source

Again, this technique is useful for reproducing builds.

BB_GENERATE_MIRROR_TARBALLS = "1"
</literallayout>
This statement tells the build system to generate mirror
tarballs.
This technique is useful if you want to create a mirror server.
If not, however, the technique can simply waste time during
the build.

Finally, consider an example where you are behind an
HTTP-only firewall.
You could make the following changes to the
<filename>local.conf</filename> configuration file as long as
the <filename>PREMIRRORS</filename> server is current:

These changes would cause the build system to successfully
fetch source over HTTP and any network accesses to anything
other than the <filename>PREMIRRORS</filename> would fail.

The build system also honors the standard shell environment
variables <filename>http_proxy</filename>,
<filename>ftp_proxy</filename>,
<filename>https_proxy</filename>, and
<filename>all_proxy</filename> to redirect requests through
proxy servers.
