This directory typically contains sets of -current snapshot binaries for NetBSD for various architectures. It also contains other experimental code. Some of these snapshots may be older than the current release, in which case you will almost certainly want the release instead. The current release is available in /pub/NetBSD . Also be aware that the snapshots placed here may very well be unstable, so only run a snapshot if you are feeling adventurous or really need a new feature such as a driver. You can find snapshots for both -current and the latest release branch from the NetBSD autobuild machines in /pub/NetBSD-daily. These snapshots might not be tested, but they probably are much more up-to-date than the manually collected snapshots in this directory.
