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.

NAME

       unshare - make local resource unavailable for mounting by remote systems

SYNOPSIS

       unshare [-p] [-F FSType] [-o specific_options]
	    [pathname | resourcename]

DESCRIPTION

       The unshare command makes a shared local resource unavailable as file system type FSType. If the option -FFSType is omitted, then the first
       file system type listed in file /etc/dfs/fstypes will be used as the default. Specific_options, as well as the semantics  of  resourcename,
       are specific to particular distributed file systems.

OPTIONS

       -F FSType

	   Specify the file system type.

       -o specific_options

	   Specify options specific to the file system provided by the -F option.

       -p

	   Remove resource from shared status in a way that persists across reboots.

FILES

       /etc/dfs/fstypes

	   Lists distributed file system utilities packages installed on the system.

       /etc/dfs/sharetab

	   Contains a table of local resources shared by the share command.

NOTES

       If pathname or resourcename is not found in the shared information, an error message will be sent to standard error.

       When  an  unshare command completes successfully, a client mounting a file system specified in that unshare command no longer has access to
       that file system.
