[[!meta title="Reproducable Builds"]]
# What is a Reproducable Build?
There are various definitions, but we will use common sense here: if I install a NetBSD release on a machine and come back to it in a year (or 10), it should be possible to create all of the installation again, 100% bitwise identical.
# Why are Reproducable Builds a good thing?
There are various advantages, one of them is the possibility to create binary patches later (after changing small things in the source, e.g. for security fixes). They are also useful if you do not trust the official builds, or are doing local builds and want to compare parts supposed to be identical.
