.Dd November 21, 2010 .Dt RUMP_TMPFS 8 .Os .Sh NAME .Nm rump_tmpfs .Nd mount a tmpfs fictional fs with a userspace server .Sh SYNOPSIS .Cd "file-system PUFFS" .Cd "pseudo-device putter"
p .Nm .Op options .Ar tmpfs .Ar mountpoint .Sh DESCRIPTION .Em NOTE! This manual page describes features specific to the .Xr rump 3 file server. Please see .Xr mount_tmpfs 8 for a full description of the available command line options.
p The .Nm utility can be used to mount tmpfs file systems. It uses .Xr rump 3 and .Xr p2k 3 to facilitate running the file system as a server in userspace. As opposed to .Xr mount_tmpfs 8 , .Nm does not use file system code within the kernel and therefore does not require kernel support except .Xr puffs 4 . Apart from a minor speed penalty there is no downside with respect to in-kernel code.
p To use .Nm via .Xr mount 8 , the flags .Fl o Ar rump and .Fl t Ar tmpfs should be given. Similarly, .Nm is used instead of .Xr mount_tmpfs 8 if .Dq rump is added to the options field of .Xr fstab 5 . .Sh SEE ALSO .Xr p2k 3 , .Xr puffs 3 , .Xr rump 3 , .Xr mount_tmpfs 8 .Sh HISTORY The .Nm utility first appeared in .Nx 5.0 .
