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
       until  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
       determinable. If not, the root's attributes are set  to  their  default
       values.


       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
               interpreted  as  a  number of megabytes. A 'g' suffix is inter‐
               preted as a number of gigabytes. A 't' suffix is interpreted as
               a  number  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
               attributes.  The default is xattr. See fsattr(7) for a descrip‐
               tion 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.


FILES

ATTRIBUTES
       See attributes(7) for descriptions of the following attributes:


       tab()  box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) ATTRIBUTE TYPEAT‐
       TRIBUTE VALUE _ Availabilitysystem/core-os

       attributes(7), fsattr(7), mount(8)

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.
