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).
rump_nfs
utility first appeared in
NetBSD 5.0.
