fstab(5)

NAME
     fstab, mtab - list of file systems to mount, mounted file system table.

SYNOPSIS
     /etc/fstab

     /etc/mtab

DESCRIPTION
     /etc/fstab is a table of file system to mount at boot time, /etc/mtab  is
     a  table  of  currently  mounted  file systems as maintained by mount and
     umount.

     These tables contain lines of  seven  fields,  the  last  three  numeric.
     Fstab may also contain empty lines, or commentary preceded by a '#'.  The
     layout is:

          device    directory    type    options    freq    pass    time

     These fields may be explained as follows:

     device
          A block special device, or a loopback mounted file or directory.

     directory
          Mount point.  For swap devices this must be swap.

     type
          One of dev, 1, 2, 1f, 2f, lo,  swap,  or  ignore,  as  explained  by
          mount(1).

     options
          A comma separated list of ro, rw, nosuid,  grpid,  nf,  swap,  user,
          noauto,  or  mkfs,  also  explained by mount(1).  The mtab file will
          only show the first six.  Either ro  or  rw  must  be  specified  in
          fstab.

     freq
          Dump frequency in days.  Tells how often a  file  system  should  be
          backed up.  (0 for no backup.)

     pass
          Pass number for a parallel fsck.  File systems will  be  checked  in
          the  order  given  by  the  pass number.  Devices with the same pass
          number will be checked in parallel.  (0 for no fsck.)

     time
          Time the file system was mounted in seconds since the  epoch.   This
          field has no meaning in fstab, so just use a 0.

FILES

     /etc/fstab     List of file systems to mount at boot time.

     /etc/mtab      List of mounted file systems.

SEE ALSO
     getmntent(3), mount(1), fsck(1), mkfs(1).

BUGS
     We could use a nice backup program and a parallel fsck.   For  the  first
     use tar(1) for now, and wait a little longer for the fsck to finish.
