RUMP_NFS(8)             NetBSD System Manager's Manual             RUMP_NFS(8)


NAME

     rump_nfs -- mount a nfs share with a userspace server


SYNOPSIS

     file-system PUFFS
     pseudo-device putter

     rump_nfs [options] share mountpoint


DESCRIPTION

     NOTE! This manual page describes features specific to the rump(3) file
     server.  Please see mount_nfs(8) for a full description of the available
     command line options.

     The rump_nfs utility can be used to mount nfs file systems.  It uses
     rump(3) and p2k(3) to facilitate running the file system as a server in
     userspace.  As opposed to mount_nfs(8), rump_nfs does not use file system
     code within the kernel and therefore does not require kernel support
     except puffs(4).  Apart from a minor speed penalty there is no downside
     with respect to in-kernel code.

     Even though the rump_nfs file system client runs within a virtual rump
     kernel in userspace, it uses host network services (by means of ``rump
     sockin'').  This means that regardless of whether using rump_nfs or
     mount_nfs(8), the same network configurations will be used.  Currently,
     ``sockin'' supports IPv4.

     To use rump_nfs via mount(8), the flags -o rump and -t nfs should be
     given.  Similarly, rump_nfs is used instead of mount_nfs(8) if ``rump''
     is added to the options field of fstab(5).
