40 .Nd mount an UDF file system
54 command attaches the UDF file system residing on the specified
56 device node on the location indicated with
59 Anonymous files stored on the UDF disc will be represented and saved in the
60 specified uid:gid pair.
61 If unspecified, it will default to nobody:nobody.
62 Both uid and gid can be either specified with their names as with
63 their numerical equivalents.
64 .Bl -tag -width XXXoptions
66 Close the session after unmount creating remountable snapshots.
67 Closing a session also allows -ROM devices to read the disc created.
68 Note that this option only makes sense when mounting sequential
69 recordable media like CD-R and DVD*R.
71 Set the group of anonymous files on the file system.
72 The default group is the nobody group.
74 Use the specified mount
81 to be mounted instead of the default last one.
82 Implements readonly snapshots on sequential media.
85 values indicate an absolute session number.
88 values are relative to the last session found on the disc.
89 Note that this option only makes sense when mounting sequential
90 recordable media like CD-R and DVD*R.
92 Set the time zone offset (in seconds) from UTC to
94 with positive values indicating east of the Prime Meridian.
95 If not set, the user's current time zone will be used.
97 Set the owner of anonymous files on the file system.
98 The default owner is the user nobody.
108 UDF is a file system defined by the OSTA standardization group and
109 is tailored for data interchange on optical discs (like CDs and
110 DVDs) between different operating systems.
111 Its also more and more common on other media like Compact
114 Read and write access is supported for all media types that CD/DVD type drives
115 can recognise including DVD-RAM.
116 BluRay support is preliminary; read-only
117 access should work fine but write support is experimental.
119 Implemented and tested media types are CD-ROM, CD-R, CD-RW, CD-MRW,
120 DVD-ROM, DVD*R, DVD*RW, DVD+MRW, DVD-RAM but the same code can also read
121 HD-DVD and BluRay discs.
122 Discs created and written by UDFclient, Nero's InCD, and Roxio's
123 DirectCD/Drag2Disc can be read without problems.
124 Both open and closed media are supported so
125 there is no need to close discs or sessions.
127 All current UDF versions up to version 2.60 are supported.
129 Hard disk partitions and
131 devices may also be mounted.
134 device it might be necessary to specify the file image sector size
139 device or the disc sector size will be used.
141 Write support for UDF version 2.50 is not completely mature and UDF version
142 2.01 should be used if possible; this is also the default format.
144 Due to lack of test media and recording devices, BluRay support and in
145 particular BluRay-R is still preliminary as of writing.
