default_fs(4)                    File Formats                    default_fs(4)



NAME
       default_fs,  fs  -  specify  the  default file system type for local or
       remote file systems

DESCRIPTION
       When file system administration commands have both specific and generic
       components (for example, fsck(1M)), the file system type must be speci-
       fied. If it is not explicitly specified using  the  -F  FSType  command
       line  option,  the  generic  command  looks  in /etc/vfstab in order to
       determine the file system type, using the supplied raw or block  device
       or  mount  point.   If  the  file  system type can not be determined by
       searching /etc/vfstab, the command will use  the  default  file  system
       type  specified in either /etc/default/fs or /etc/dfs/dfstypes, depend-
       ing on whether the file system is local or remote.

       The default local file system type is specified in /etc/default/fs by a
       line  of  the  form  LOCAL=fstype (for example, LOCAL=ufs). The default
       remote file system type  is  determined  by  the  first  entry  in  the
       /etc/dfs/fstypes file.

       File  system  administration  commands  will determine whether the file
       system is local or remote by examining the specified device  name.   If
       the  device   name  starts  with  ``/'' (slash), it is considered to be
       local; otherwise it is remote.

       The default file system types can be changed  by  editing  the  default
       files with a text editor.
