This article describes building an internal <application>FreeBSD Update Server</application>. The <link xlink:href="https://svnweb.freebsd.org/base/user/cperciva/freebsd-update-build/">freebsd-update-server</link> is written by Colin Percival <email>cperciva@FreeBSD.org</email>, Security Officer Emeritus of FreeBSD. For users that think it is convenient to update their systems against an official update server, building their own <application>FreeBSD Update Server</application> may help to extend its functionality by supporting manually-tweaked FreeBSD releases or by providing a local
mirror that will allow faster updates for a number of machines.
