ATTRIBUTES

       The  following  is  a  list  of  filesystem properties which may be queried as methods through the parent
       Sys::Filesystem object.

       fs_spec
           Describes the block special device or remote filesystem to be mounted.

           For  ordinary  mounts  it  will hold (a link to) a block special device node (as created by mknod(8))
           for  the  device  to  be  mounted, like '/dev/cdrom' or '/dev/sdb7'.  For NFS mounts one  will   have
           <host>:<dir>, e.g., 'knuth.aeb.nl:/'.  For procfs, use 'proc'.

           Instead  of  giving the device explicitly, one may indicate the (ext2  or xfs)  filesystem that is to
           be mounted by its UUID or volume label (cf.  e2label(8) or   xfs_admin(8)),   writing   LABEL=<label>
           or   UUID=<uuid>,  e.g., 'LABEL=Boot' or 'UUID=3e6be9de-8139-11d1-9106-a43f08d823a6'.  This will make
           the system more robust: adding or removing a  SCSI  disk changes the disk device  name  but  not  the
           filesystem volume label.

       fs_file
           Describes  the mount point for the filesystem. For swap partitions, this field should be specified as
           'none'. If the name of the mount point contains spaces these can be escaped as '\040'.

       fs_vfstype
           Dscribes the type  of  the  filesystem.  Linux  supports  lots  of filesystem types,  such  as  adfs,
           affs,  autofs,  coda,  coherent, cramfs, devpts, efs, ext2, ext3,  hfs,  hpfs,  iso9660, jfs,  minix,
           msdos,  ncpfs,  nfs,  ntfs,  proc, qnx4, reiserfs, romfs, smbfs, sysv, tmpfs, udf, ufs, umsdos, vfat,
           xenix,  xfs,  and  possibly others.  For more details, see mount(8).  For the  filesystems  currently
           supported  by  the running kernel, see /proc/filesystems.  An entry  swap denotes a file or partition
           to be used for swapping, cf. swapon(8).  An entry ignore causes the line to  be  ignored.   This   is
           useful  to  show disk partitions which are currently unused.

       fs_mntops
           Describes the mount options associated with the filesystem.

           It is formatted as a comma separated list of options.  It  contains  at least  the type of mount plus
           any  additional  options  appropriate  to  the  filesystem  type.  For documentation on the available
           options  for  non- nfs  file systems, see mount(8).  For documentation on  all  nfs-specific  options
           have  a  look  at nfs(5).  Common for all types of file system are the options 'noauto' (do not mount
           when 'mount -a' is given, e.g., at boot time), 'user'  (allow  a  user   to   mount),   and   'owner'
           (allow device  owner to mount), and '_netdev' (device requires network to be available).  The 'owner'
           and '_netdev' options are  Linux-specific.  For more details, see mount(8).

       fs_freq
           Used   for   these  filesystems  by  the  dump(8)  command  to determine which filesystems need to be
           dumped.   If the  fifth  field  is not present, a value of zero is returned and dump will assume that
           the filesystem does not need to be dumped.

       fs_passno
           Used by the fsck(8) program to  determine the order in which filesystem checks  are  done  at  reboot
           time.   The  root  filesystem  should  be  specified  with a fs_passno of  1,  and  other filesystems
           should  have a fs_passno of 2.   Filesystems  within  a  drive  will  be  checked  sequentially,  but
           filesystems  on  different  drives   will  be   checked   at   the   same time to utilize parallelism
           available in the hardware.  If the sixth field is not present or zero, a value  of  zero is  returned
           and fsck will assume that the filesystem does not need to be checked.
