NAME

       Sys::Filesystem::Linux - Return Linux filesystem information to Sys::Filesystem

SYNOPSIS

       See Sys::Filesystem.

INHERITANCE

	 Sys::Filesystem::Linux
	 ISA Sys::Filesystem::Unix
	   ISA UNIVERSAL

METHODS

       version ()
	   Return the version of the (sub)module.

ATTRIBUTES

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

       fs_spec
	   Dscribes 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/cdromaXX   or   aXX/dev/sdb7aXX.    For	 NFS   mounts  one  will  have <host>:<dir>, e.g., aXXknuth.aeb.nl:/aXX.
	   For procfs, use aXXprocaXX.

	   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.,   aXXLABEL=BootaXX   or
	   aXXUUID=3e6be9de-8139-11d1-9106-a43f08d823a6aXX.  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 asaXXnone. If the name of the mount
	   point contains spaces these can be escaped asaXX40.

       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
	   aXXaXXnoautoaXXaXX (do not mount when 'mount -a' is given, e.g., at boot time), aXXaXXuseraXXaXX (allow a user  to  mount),	and
	   aXXaXXowneraXXaXX  (allow device  owner to mount), and aXXaXX_netdevaXXaXX (device requires network to be available).  The
	   aXXaXXowneraXXaXX and aXXaXX_netdevaXXaXX 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.
