51.Sh SYNOPSIS
52.Nm mount_ Ns Ar fsname
53.Op Fl o Ar options
54.Ar "fs"
55.Ar mount_point
56.Sh DESCRIPTION
57The
58.Nm
59command is a generic mechanism for attaching ``standard'' filesystems to
60the filesystem.  The
61.Nm
62command currently supports the following filesystems:
63.Nm fdesc ,
64.Nm linprocfs
65and
66.Nm procfs .
67A ``standard'' filesystem is one which:
68.Bl -enum -offset indent
69.It
70accepts only the standard
71.Fl o
72options
73.Dq ro
74.Pq Dq rdonly ,
75.Dq rw ,
76.Dq nodev ,
77.Dq noexec ,
78.Dq nosuid ,
79and
80.Dq union .
81.It
82has a kernel filesystem module name the same as its user-visible name.
83.It
84requires no other special processing on the part of the
85.Nm
86command.
87.El
88.Pp
89The options are as follows:
90.Bl -tag -width indent
91.It Fl o
92Options are specified with a
93.Fl o
94flag followed by a comma separated string of options.
95See the
96.Xr mount 8
97man page for possible options and their meanings.
98.El
99.Pp
100The
101.Nm
102command examines its zeroth command-line argument (the name by which
103it was called) to determine the type of filesystem to be mounted.  If
104it is called by a name which does not end in
105.Dq Li _ Ns Ar fsname ,
106.Nm
107will assume (for compatibility
108with
109.Xr mount 8 )
110that the zeroth argument contains only the name of the filesystem type.
111The
112.Nm
113command is normally installed with appropriate links to commands for
114the distributed filesystems which can be mounted in this way;
115for information on the function of each filesystem, see the manual page
116for that specific
117.Nm mount_ Ns Ar fsname
118command.
119.Pp
120Refer to the following manual pages for detailed information
121on these file system:
122.Xr fdesc 5 ,
123.Xr linprocfs 5
124and
125.Xr procfs 5 .
126.Sh DIAGNOSTICS
127.Bl -diag
128.It argv[0] must end in _fsname
129.Nm Mount_std
130was called with a zeroth argument of
131.Dq Li mount_std .
132.It vfsload(%s)
133.Nm Mount_std
134was unable to load a kernel module implementing the %s filesystem
135type.
136.It %s filesystem not available
137The specified filesystem type was not present in the kernel and no
138loadable module for it was found.
