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.
