mount_tmpfs(8) System Administration Commands mount_tmpfs(8)
NAME
mount_tmpfs - mount tmpfs file systems
SYNOPSIS
mount [-F tmpfs] [-o specific_options] [-O] special mount_point
DESCRIPTION
tmpfs is a memory based file system which uses kernel resources relat‐
ing to the VM system and page cache as a file system.
mount attaches a tmpfs file system to the file system hierarchy at the
pathname location mount_point, which must already exist. If mount_point
has any contents prior to the mount operation, these remain hidden un‐
til the file system is once again unmounted. The attributes (mode,
owner, and group) of the root of the tmpfs filesystem are inherited
from the underlying mount_point, provided that those attributes are de‐
terminable. If not, the root's attributes are set to their default val‐
ues.
The special argument is usually specified as swap but is in fact disre‐
garded and assumed to be the virtual memory resources within the sys‐
tem.
OPTIONS
-o specific_options
Specify tmpfs file system specific options in a comma-separated
list with no intervening spaces. If invalid options are specified,
a warning message is printed and the invalid options are ignored.
The following options are available:
size=sz
The sz argument controls the size of this particular tmpfs file
system. If the argument is has a 'k' suffix, the number will be
interpreted as a number of kilobytes. An 'm' suffix will be in‐
terpreted as a number of megabytes. A 'g' suffix is interpreted
as a number of gigabytes. A 't' suffix is interpreted as a num‐
ber of terabytes. No suffix is interpreted as bytes. In all
cases, the actual size of the file system is the number of
bytes specified, rounded up to the physical pagesize of the
system.
xattr | noxattr
Allow or disallow the creation and manipulation of extended at‐
tributes. The default is xattr. See fsattr(7) for a description
of extended attributes.
-O
Overlay mount. Allow the file system to be mounted over an existing
mount point, making the underlying file system inaccessible. If a
mount is attempted on a pre-existing mount point without setting
this flag, the mount will fail, producing the errordevice busy.

NOTES
If the directory on which a file system is to be mounted is a symbolic
link, the file system is mounted on the directory to which the symbolic
link refers, rather than on top of the symbolic link itself.
