Branches: MAIN
CVS tags: HEAD
Move existing project definitions from projects/gsoc_2011/ to
projects/project/ .

The goal for this reorganization is to remove any knowledge of the projects
classification from the file hierarchy: the classification goes into tags,
and projects indexes automatically list projects based on such tags.

Also, the current gsoc_2011 name was wrong anyway, because GSoC 2011 has
already concluded and projects would have had to move to a gsoc_2012 directory

Lastly, yes, "projects/project/*" is slightly redundant.  But I want to keep
the project lists from the projects "database" clearly separated.

This is as proposed in www@.

title="Improved Automounter Support"


[Matthias Scheler](

duration="3 months"

NetBSD currently uses [The Berkeley Automounter Suite of Utilities]( for automatically mounting (network) file systems. This software package implements an automounter file system as a userland NFS daemon. While this generally works it has major drawbacks:

* File systems are not mounted directly on the desired mount point. As a result applications frequently use incorrect pathnames (e.g. `/amd/server/home/user` instead of `/home/user`) for automatically mounted directories or files beneath them. This is especially problematic in heterogeneous enviroments where not all machines use the same automounter.
* The automounter daemon cannot handle high I/O load very well, file access occasionally fails with intermittent errors.

The goal of this project is to implement a new automounter solution which addresses the above issues. This could either be done via a Solaris/Linux compatible autofs(4) full in-kernel file system or via a userland daemon using [puffs](
