Name
       fstab - file containing static information about known file systems

Description
       The file contains descriptive information about the known file systems.
       By convention, is created and maintained as a  read-only	 file  by  the
       system  administrator.	Each  file system is described by its own line
       within The order of these lines and the file systems they represent  is
       important  because and sequentially process in the performance of their
       tasks.

       The format of each file system description in is as follows:
       spec:file:type:freq:passno:name:options
       The meanings of these fields are:

       spec	 The block special file name of the device on which  the  file
		 system is located.  It can also be a network name for such as
		 or

       file	 The pathname of the directory on which	 the  file  system  is
		 mounted.

       type	 How  the  file	 system	 is mounted.  The ways in which a file
		 system can be mounted are:
		 rw - mount the file system read-write
		 ro - mount the file system read only
		 rq - mount the file system read-write with quotas
		 sw - make the special file part of the swap space
		 xx - ignore the entry

       freq	 The frequency (in days) with which the command dumps the  rw,
		 ro, and rq file systems.

       passno	 The order in which the command checks the rw, ro, and rq file
		 systems at reboot time.

       name	 The name of the file system type.  File systems can have  the
		 following  types:  ufs	 --  ULTRIX file system and nfs -- SUN
		 Network file system.

       options	 The options field.  This field contains an  arbitrary	string
		 meaningful only when mounting file systems with the specified
		 file system type name, such as NFS.  The specific options are
		 described in the reference pages.

       Special actions occur for file systems of type sw and rq at system boot
       time.  File systems of type sw are made part of the swap space  by  the
       command	and disk quotas are automatically processed by the command and
       then enabled by the command for rq file systems.

Examples
       Here is a sample file:
       /dev/ra0a:/:rw:1:1:ufs::
       /dev/ra1g:/usr:rw:1:2:ufs::
       /@bigvax:/bigvax:rw:0:0:nfs::
       /usr/uws2.0@bigvax:/usr/uws2.0:rw:0:0:nfs:soft,bg,nosuid:
       /usr/dec@bigvax:/usr/dec:rw:0:0:nfs:bg,soft,nosuid:
       /usr/pro/xyz@vax:/usr/pro/xyz:rw:0:0:nfs:bg,soft,intr,nosuid:
       The last three entries in the sample shown use NFS options as described
       in the reference page.

Restrictions
       The  passno  field  of  the  root file system should be specified as 1.
       Other file systems should have larger values.  File systems on the same
       device  should  have distinct passno fields.  File systems on different
       devices may have the identical passno fields to allow them to be simul‐
       taneously checked.

       All  field  delimiters  (:) must exist within each file system descrip‐
       tion; only the options field may not be	present.   However,  only  the
       fields  spec  and  type	are meaningful to sw file systems and only the
       type field is meaningful to xx file systems.

       The file system description within should be parsed only through use of
       the routines.
