   18: NetBSD currently uses amd 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:
   19: 
   20: * 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.
   21: * The automounter daemon cannot handle high I/O load very well; file access occasionally fails with intermittent errors.
   22: 
   23: The milestones of this project are:
   24: 
   25: * implement a new automounter solution which has configurable mount points
   26: * improve high I/O
   27: * show benchmarks and implement automated tests
   28: 
   29: This could either be done via a Solaris/Linux compatible autofs(4) full in-kernel file system. FreeBSD has already implemented autofs, so we could port theirs and that should significantly simplify the project.
