NAME
dump9660, mk9660 - create an ISO-9660 CD image
SYNOPSIS
disk/mk9660 [ -:D ] [ -9cjr ] [ -b bootfile ] [ -B bootfile [ -x loader
] ] [ -p proto ] [ -s src ] [ -v volume ] image
disk/dump9660 [ -:D ] [ -9cjr ] [ -p proto ] [ -s src ] [ -v volume ] [
-m maxsize ] [ -n now ] image
DESCRIPTION
Mk9660 writes to the random access file image an ISO-9660 CD image con‐
taining the files named in proto (by default, /sys/lib/syscon‐
fig/proto/portproto) from the file tree src (by default, the current
directory). The proto file is formatted as described in mkfs(8).
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 di‐
rectory entry will be populated with Plan directory information (owner,
group, mode, full name); this is interpreted by 9660srv.
If the -j flag is given, the usual directory tree is written, 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 for‐
mat of the system use sharing protocol; this format 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 use‐
ful 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. Additionally, -x can be
used in conjunction with -B to make mk9660 annotate the boot file with
the address and size of the loader, which has to be a file in the CD's
root directory.
The -D flag creates immense amounts of debugging output on standard er‐
ror.
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 conformant
ISO-9660 directory tree, Plan 9 extensions in the system use fields,
and a Joliet directory tree.
