     tmpfs — efficient memory file system

     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):


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

     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.

     To mount a tmpfs memory file system:

	   mount -t tmpfs tmpfs /tmp

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

     The tmpfs driver first appeared in FreeBSD 7.0.

     The tmpfs kernel implementation was written by Julio M. Merino Vidal
     ⟨⟩ as a Google SoC project.

     Rohit Jalan and others ported it from NetBSD to FreeBSD.

     This manual page was written by Xin LI ⟨⟩.

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