+<p>If you’re building system images, you’re going to do a lot of debootstrap, which is going to fetch a lot of packages. On a fast system, that’ll be the slowest part of the process. Here’s how to cache.</p>
+
+<h3>Install apt-cacher-ng</h3>
+
+<code>sudo apt-get install squid-deb-proxy</code>
+
+<h3>Tell programs to use the proxy</h3>
+
+<code>export http_proxy=http://127.0.0.1:8000
+# Note that you'll need to re-export this before any use of debootstrap</code>
+
+<h3>Tell sudo to pass through http_proxy</h3>
+
+<code>sudo visudo
+# Add the line after the env_reset line:
+Defaults env_keep += "http_proxy"</code>
