DESCRIPTION
Mk9660 writes to the random access file image an ISO-9660 CD
image containing the files named in proto (by default,
/sys/lib/sysconfig/proto/portproto) from the file tree src
(by default, the current directory). The proto file format
is described in proto(2).
The created CD image will be in ISO-9660 format, but by
default the file names will be stored in UTF-8 with no
imposed length or character restrictions. The -c flag
causes mk9660 to use only file names in ``8.3'' form that
use digits, letters, and underscore. File names that do not
conform are changed to Dnnnnnn (for directories) or Fnnnnnn
(for files); a key file _CONFORM.MAP is created in the root
directory to ease the reverse process.
If the -9 flag is given, the system use fields at the end of
each directory entry will be populated with Plan directory
information (owner, group, mode, full name); this is inter-
preted by 9660srv.
If the -j flag is given, the usual directory tree is writ-
ten, but an additional tree in Microsoft Joliet format is
also added. This second tree can contain long Unicode file
names, and can be read by 9660srv as well as most versions
of Windows and many Unix clones. The characters *, :, ;, ?,
and \ are allowed in Plan 9 file names but not in Joliet
file names; non-conforming file names are translated and a
_CONFORM.MAP file written as in the case of the -c option.
If the -r flag is given, Rock Ridge extensions are written
in the format of the system use sharing protocol; this for-
mat provides Posix-style file metadata and is common on Unix
platforms.
The options -c, -9, -j, and -r may be mixed freely with the
exception that -9 and -r are mutually exclusive.
The -v flag sets the volume title; if unspecified, the base

name of proto is used.
The -: flag causes mk9660 to replace colons in scanned file
names with spaces; this is the inverse of the map applied by
dossrv(4) and is useful for writing Joliet CDs containing
data from FAT file systems.
The -b option creates a bootable CD. Bootable CDs contain
pointers to floppy images which are loaded and booted by the
BIOS. Bootfile should be the name of the floppy image to
use; it is a path relative to the root of the created CD.
That is, the boot floppy image must be listed in the proto
file already: the -b option just creates a pointer to it.
The -B option is similar to -b but the created CD image is
marked as having a non-floppy-emulation boot block. This
gives the program in the boot block full (ATA) LBA access to
the CD filesystem, not just the initial blocks that would
fit on a floppy.
In addition to -b and -B a boot entry for UEFI systems can
be created with the -E option and with bootfile pointing to
a FAT image containing the contents of the efi system parti-
tion.
The -D flag creates immense amounts of debugging output on
standard error.
Dump9660 is similar in specification to mk9660 but creates
and updates backup CD images in the style of the dump file
system (see fs(4)). The dump is file-based rather than
block-based: if a file's contents have not changed since the
last backup, only its directory entry will be rewritten.
The -n option specifies a time (in seconds since January 1,
1970) to be used for naming the dump directory.
The -m option specifies a maximum size for the image; if a
backup would cause the image to grow larger than maxsize, it
will not be written, and dump9660 will exit with a non-empty
status.
EXAMPLE
Create an image of the Plan 9 source tree, including a con-
formant ISO-9660 directory tree, Plan 9 extensions in the
system use fields, and a Joliet directory tree.
