Hackathon 16

The 16th NetBSD hackathon is running until February 12th. Our goal is fixing all the bugs that need fixing to get NetBSD-current ready for the creation of the NetBSD 6.0 release branch.

Join us on the IRC channel #netbsd-code on freenode (irc.freenode.net). Just join, have a look around and ask your questions or what work needs to be done.

Primary goals

We want NetBSD 6.0 to be the best NetBSD release ever. There are already a lot of great features in it:

Improved kernel performance and scalability
New kernel module framework with automatic module loading
Logical Volume Manager
NetBSD Packet Filter
Xen SMP support
Flash file-system CHFS
Automated Regression Testing
Improved FUSE support
Updated Linux emulation
GCC 4.5.3
Updated X.org X11 distribution
SMTP authentication client built into Postfix (now version 2.8.7)
New and enhanced drivers
... and many other features

To make sure that NetBSD users get the best possible experience of the new release we would like to fix as many as possible of the following bugs. If you are able to help us to fix these bugs by supplying patches or testing fixes please consider to participate. We are also in need of people to supply documentation fixes, preferably in the form of patches. Release notes and/or manual pages!
