77 file is formatted as described in
80 The created CD image will be in ISO-9660
81 format, but by default the file names will
82 be stored in UTF-8 with no imposed length
83 or character restrictions.
88 to use only file names in ``8.3'' form
89 that use digits, letters, and underscore.
90 File names that do not conform are changed
99 is created in the root
100 directory to ease the reverse process.
104 flag is given, the system use fields at the end of
105 each directory entry will be populated with
106 Plan directory information (owner, group, mode,
107 full name); this is interpreted by
112 flag is given, the usual directory tree is written,
113 but an additional tree in Microsoft Joliet format is
115 This second tree can contain long Unicode file names,
118 as well as most versions of Windows
119 and many Unix clones.
127 are allowed in Plan 9 file names but not in Joliet file names;
128 non-conforming file names are translated
132 as in the case of the
138 flag is given, Rock Ridge extensions are written in the
139 format of the system use sharing protocol;
140 this format provides Posix-style file metadata and is
141 common on Unix platforms.
149 may be mixed freely with the exception that
153 are mutually exclusive.
157 flag sets the volume title;
158 if unspecified, the base name of
166 to replace colons in scanned file names with spaces;
167 this is the inverse of the map applied by
169 and is useful for writing Joliet CDs containing data
170 from FAT file systems.
174 option creates a bootable CD.
175 Bootable CDs contain pointers to floppy images which are
176 loaded and booted by the BIOS.
178 should be the name of the floppy image to use;
179 it is a path relative to the root of the created CD.
180 That is, the boot floppy image must be listed in the
185 option just creates a pointer to it.
191 but the created CD image is marked as having a non-floppy-emulation
193 This gives the program in the boot block full (ATA) LBA access
194 to the CD filesystem, not just the initial blocks that would fit on a floppy.
198 flag creates immense amounts of debugging output
202 is similar in specification to
204 but creates and updates backup CD images in the style of
210 The dump is file-based rather than block-based:
211 if a file's contents have not changed since the last
212 backup, only its directory entry will be rewritten.
216 option specifies a time (in seconds since January 1, 1970)
217 to be used for naming the dump directory.
221 option specifies a maximum size for the image;
222 if a backup would cause the image to grow larger than
224 it will not be written, and
226 will exit with a non-empty status.
229 Create an image of the Plan 9 source tree,
230 including a conformant ISO-9660 directory tree,
231 Plan 9 extensions in the system use fields, and
232 a Joliet directory tree.
