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).
