This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

.Sh SYNOPSIS
|
|
.Nm mount_ Ns Ar fsname

.Ar "fs"
|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command is a generic mechanism for attaching ``standard'' filesystems to
|
|
the filesystem. The
|
|
.Nm
|
|
command currently supports the following filesystems:
|
|
.Nm devfs ,
|
|
.Nm fdesc ,
|
|
.Nm kernfs
|
|
and
|
|
.Nm procfs .
|
|
A ``standard'' filesystem is one which:
|
|
.Bl -enum -offset indent
|
|
.It
|
|
accepts only the standard
|
|
.Fl o
|
|
options
|
|
.Dq ro
|
|
.Pq ``rdonly'' ,
|
|
.Dq rw ,
|
|
.Dq nodev ,
|
|
.Dq noexec ,
|
|
.Dq nosuid ,
|
|
and
|
|
.Dq union .
|
|
.It
|
|
has a kernel filesystem module name the same as its user-visible name.
|
|
.It
|
|
requires no other special processing on the part of the
|
|
.Nm mount_std
|
|
command.
|
|
.El
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width indent
|
|
.It Fl o
|
|
Options are specified with a
|
|
.Fl o
|
|
flag followed by a comma separated string of options.
|
|
See the
|
|
.Xr mount 8
|
|
man page for possible options and their meanings.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Nm
|
|
command examines its zeroth command-line argument (the name by which
|
|
it was called) to determine the type of filesystem to be mounted. If
|
|
it is called by a name which does not end in
|
|
.Dq Li _ Ns Ar fsname ,
|
|
.Nm
|
|
will assume (for compatibility
|
|
with
|
|
.Xr mount 8 )
|
|
that the zeroth argument contains only the name of the filesystem type.
|
|
The
|
|
.Nm
|
|
command is normally installed with appropriate links to commands for
|
|
the distributed filesystems which can be mounted in this way;
|
|
for information on the function of each filesystem, see the manual page
|
|
for that specific
|
|
.Nm mount_ Ns Ar fsname
|
|
command.
|
|
.Pp
|
|
Refer to the following manual pages for detailed information
|
|
on these file system:
|
|
.Xr devfs 5 ,
|
|
.Xr fdesc 5 ,
|
|
.Xr kernfs 5
|
|
and
|
|
.Xr procfs 5 .
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It argv[0] must end in _fsname
|
|
The
|
|
.Nm mount_std
|
|
command was called with a zero'th argument of
|
|
.Dq Li mount_std .
|
|
.It vfsload(%s)
|
|
.Nm
|
|
was unable to load a kernel module implementing the %s filesystem
|
|
type.
|
|
.It %s filesystem not available
|
|
The specified filesystem type was not present in the kernel and no
|
|
loadable module for it was found.
