New initiative for binary updates effort.

This is a best effort service to provide builds of the stable tree of OpenBSD (only kernel + userland, no file sets for X at the moment).

The goal is to build a new release(8) once a month and after a security fix is published. As this is done by a small group of volunteers, no guarantees can be given in any way.

These files can be used to install OpenBSD or update the system. If you are updating, don't untar the etcXX.tgz file, unless you want to wipe out your local configuration. See the OpenBSD FAQ for further instructions.

Please note that these files are not provided by the OpenBSD project. If you don't trust them, don't use them. Build your own binaries, (http://www.openbsd.org/stable.html) hire someone to do it for you or wait for the next release.

If you think something is missing or broken, please send an email to openbsd at z74 dot net.

Binary available here: ftp://ftp.su.se/pub/mirrors/openbsd_stable/

Thanks.

Get KDE and KDM going
