NAME
fs_wrapper - configuration and binary files used by file system administration commands

mkfs [-F FStype ] ...

ncheck [-F FStype ] ...
newfs [-F FStype ] ...
quot [-F FStype ] ...
quotacheck [-F FStype ] ...
volcopy [-F FStype ] ...
DESCRIPTION
The commands listed in the SYNOPSIS can operate on different types of file systems. Each command
(except for
mount) reads file system specific configuration files that control the command’s behavior, and
invokes a file system specific binary file to do the actual work. FStype is the file system type as optionally
specified on the command line. If FStype is not given, then the file system type is determined from
/etc/fstab by matching an entry in this file with a device special provided with the command (see
individual commands for details of usage).
Administrators may also define a default file system type for the above commands via the file
/etc/default/fs. If this file exists, and contains the line:
LOCAL=FStype
(e.g.,
LOCAL=hfs), then the above commands will assume the FStype given in /etc/default/fs
,
unless an FStype is provided on the command line or is in
/etc/fstab. The default file system
specification is provided to maintain compatibility with pre-10.0 invocations of the commands.
See the FILES section for a list of the files used.
WARNINGS
The configuration files /sbin/lib/mfsconfig.d/
FStype are supplied by HP or by other file system
vendors. They are not meant to be edited by System Administrators. Corruption or removal of these files
may lead to strange behavior, including the inability to boot.
The format of the configuration file is subject to change.
The file system specific binary files are not normally executed directly. However, if the configuration files
become unusable, direct execution of these binary files may be a useful step in repairing and running the
system again. The binary files accept the same arguments as the commands by which they are executed.
The
mount command is a special case. This command currently does not read a configuration file, and
does not execute a file system specific binary file if FStype is cdfs, hfs, nfs,orlofs. The binary that
handles these FStype s also processes other FStype s and calls the file system specific command if
appropriate.
For historical reasons, the
hfs binary files also handle nfs and cdfs, so there are no separate binary
files for the latter two file systems.
The commands (except
mount) will not work if they are renamed, because they are symbolically linked to
a single executable (/sbin/fs_wrapper).
