81 file is formatted as described in
84 The created CD image will be in ISO-9660
85 format, but by default the file names will
86 be stored in UTF-8 with no imposed length
87 or character restrictions.
92 to use only file names in ``8.3'' form
93 that use digits, letters, and underscore.
94 File names that do not conform are changed
103 is created in the root
104 directory to ease the reverse process.
108 flag is given, the system use fields at the end of
109 each directory entry will be populated with
110 Plan directory information (owner, group, mode,
111 full name); this is interpreted by
116 flag is given, the usual directory tree is written,
117 but an additional tree in Microsoft Joliet format is
119 This second tree can contain long Unicode file names,
122 as well as most versions of Windows
123 and many Unix clones.
131 are allowed in Plan 9 file names but not in Joliet file names;
132 non-conforming file names are translated
136 as in the case of the
142 flag is given, Rock Ridge extensions are written in the
143 format of the system use sharing protocol;
144 this format provides Posix-style file metadata and is
145 common on Unix platforms.
153 may be mixed freely with the exception that
157 are mutually exclusive.
161 flag sets the volume title;
162 if unspecified, the base name of
170 to replace colons in scanned file names with spaces;
171 this is the inverse of the map applied by
173 and is useful for writing Joliet CDs containing data
174 from FAT file systems.
178 option creates a bootable CD.
179 Bootable CDs contain pointers to floppy images which are
180 loaded and booted by the BIOS.
182 should be the name of the floppy image to use;
183 it is a path relative to the root of the created CD.
184 That is, the boot floppy image must be listed in the
189 option just creates a pointer to it.
195 but the created CD image is marked as having a non-floppy-emulation
197 This gives the program in the boot block full (ATA) LBA access
198 to the CD filesystem, not just the initial blocks that would fit on a floppy.
204 a boot entry for UEFI systems can be created with the
208 pointing to a FAT image containing the contents of
209 the efi system partition.
213 flag creates immense amounts of debugging output
217 is similar in specification to
219 but creates and updates backup CD images in the style of
225 The dump is file-based rather than block-based:
226 if a file's contents have not changed since the last
227 backup, only its directory entry will be rewritten.
231 option specifies a time (in seconds since January 1, 1970)
232 to be used for naming the dump directory.
236 option specifies a maximum size for the image;
237 if a backup would cause the image to grow larger than
239 it will not be written, and
241 will exit with a non-empty status.
244 Create an image of the Plan 9 source tree,
245 including a conformant ISO-9660 directory tree,
246 Plan 9 extensions in the system use fields, and
247 a Joliet directory tree.
