.SH NAME
default_fs, fs \- specify the default file system type for local or remote file
systems
.SH DESCRIPTION
.sp
.LP
When file system administration commands have both specific and generic
components (for example, \fBfsck\fR(1M)), the file system type must be
specified. If it is not explicitly specified using the \fB-F\fR \fIFSType\fR
command line option, the generic command looks in \fB/etc/vfstab\fR 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
\fB/etc/vfstab\fR, the command will use the default file system type specified
in either \fB/etc/default/fs\fR or \fB/etc/dfs/dfstypes\fR, depending on
whether the file system is local or remote.
.sp
.LP
The default local file system type is specified in \fB/etc/default/fs\fR by a
line of the form \fBLOCAL=\fR\fIfstype\fR (for example, \fBLOCAL=ufs\fR). The
default remote file system type is determined by the first entry in the
\fB/etc/dfs/fstypes\fR file.
.sp
.LP
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.
.sp
.LP
The default file system types can be changed by editing the default files with
a text editor.
