rump_tmpfs -- mount a tmpfs fictional fs with a userspace server
rump_tmpfs [options] tmpfs mountpoint
NOTE! This manual page describes features specific to the rump(3) file
server. Please see mount_tmpfs(8) for a full description of the avail-
able command line options.
The rump_tmpfs utility can be used to mount tmpfs file systems. It uses
rump(3) and p2k(3) to facilitate running the file system as a server in
userspace. As opposed to mount_tmpfs(8), rump_tmpfs does not use file
system code within the kernel and therefore does not require kernel sup-
port except puffs(4). Apart from a minor speed penalty there is no down-
side with respect to in-kernel code.
To use rump_tmpfs via mount(8), the flags -o rump and -t tmpfs should be
given. Similarly, rump_tmpfs is used instead of mount_tmpfs(8) if
``rump'' is added to the options field of fstab(5).

The rump_tmpfs utility first appeared in NetBSD 5.0.
