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
       specified. 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.
