NAME
     tmpfs — efficient memory file system

SYNOPSIS
     To compile this driver into the kernel, place the following line in your
     kernel configuration file:

	   options TMPFS

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

	   tmpfs_load="YES"

DESCRIPTION
     The tmpfs driver will permit the FreeBSD kernel to access tmpfs file sys‐
     tems.

OPTIONS
     The following options are available when mounting tmpfs file systems:

     gid     root group id.

     uid     root user id.

     mode    permissions in octal format.

     inodes  maximum number of inodes.

     size    maximum size (in bytes) for the file system.

	   mount -t tmpfs tmpfs /tmp

SEE ALSO
     nmount(2), unmount(2), fstab(5), mount(8)

HISTORY
     The tmpfs driver first appeared in FreeBSD 7.0.

AUTHORS
     The tmpfs kernel implementation was written by Julio M. Merino Vidal
     ⟨jmmv@NetBSD.org⟩ as a Google SoC project.

     Rohit Jalan and others ported it from NetBSD to FreeBSD.

     This manual page was written by Xin LI ⟨delphij@FreeBSD.org⟩.

BUGS
     The tmpfs kernel implementation is currently considered as an experimen‐
     tal feature.  Some file system mount time options are not well supported.
