52.Sh DESCRIPTION
53The
54.Nm
55utility attaches the ISO-9660 file system residing on the device
56.Pa special
57to the global file system namespace at the location indicated by
58.Pa node .
59This command is normally executed by
60.Xr mount 8
61at boot time.
62.Pp
63The options are as follows:
64.Bl -tag -width indent
65.It Fl b
66Relax checking for Supplementary Volume Descriptor Flags field
67which is set to a wrong value on some Joliet formatted disks.
68.It Fl e
69Enable the use of extended attributes.
70.It Fl g
71Do not strip version numbers on files.
72(By default, if there are files with different version numbers on the disk,
73only the last one will be listed.)
74In either case, files may be opened without explicitly stating a
75version number.
76.It Fl j
77Do not use any Joliet extensions included in the file system.
f50c51ce
AP
78.It Fl L Ar locale
79Specify locale name used for internal filename conversions.
984263bc

80.It Fl o
81Options are specified with a
82.Fl o
83flag followed by a comma separated string of options.
84See the
85.Xr mount 8
86man page for possible options and their meanings.
87The following cd9660 specific options are available:
88.Pp
89.Bl -tag -width "nostrictjoliet" -compact
90.It Cm extatt
91Same as
92.Fl e .
93.It Cm gens
94Same as
95.Fl g .
96.It Cm nojoliet
97Same as
98.Fl j .
99.It Cm norrip
100Same as
101.Fl r .
102.It Cm nostrictjoliet
103Same as
104.Fl b .
105.El
106.It Fl r
107Do not use any Rockridge extensions included in the file system.
108.It Fl s Ar startsector
109Start the file system at
110.Ar startsector .
111Normally, if the underlying device is a CD-ROM drive,
112.Nm
113will try to figure out the last track from the CD-ROM containing
114data, and start the file system there. If the device is not a CD-ROM,
115or the table of contents cannot be examined, the file system will be
116started at sector 0. This option can be used to override the behaviour.
117Note that
118.Ar startsector
119is measured in CD-ROM blocks, with 2048 bytes each. This is the same
120as for example the
121.Cm info
122command of
123.Xr cdcontrol 1
124is printing.
125It is possible to mount an arbitrary session of a multi-session CD by specifying
126the correct
127.Ar startsector
128here.
129.It Fl v
130Be verbose about the starting sector decisions made.
131.El
132.Sh EXAMPLES
133The following command can be used to mount a Kodak Photo-CD:
134.Pp
135.Dl "mount_cd9660 -o rw -v -s 0 /dev/cd0c /cdrom"

142.Sh HISTORY
143The
144.Nm
145utility first appeared in
146.Bx 4.4 .

MD
147.Sh BUGS
148POSIX device node mapping is currently not supported.
149.Pp
150Version numbers are not stripped if Rockridge extensions are in use.
151In this case, accessing files that don't have Rockridge names without
152version numbers gets the one with the lowest version number and not
153the one with the highest.
154.Pp
155There is no ECMA support.
