.SH DESCRIPTION
|
|
.I Mk9660
|
|
writes to the random access file
|
|
.I image
|
|
an ISO-9660 CD image containing the
|
|
files named in
|
|
.I proto
|
|
(by default,
|
|
.BR /sys/lib/sysconfig/proto/portproto )
|
|
from the file tree
|
|
.I src
|
|
(by default,
|
|
the current directory).
|
|
The
|
|
.I proto
|
|
file format is described in
|
|
.IR proto (2).
|
|
.PP
|
|
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
|
|
.B -c
|
|
flag causes
|
|
.I 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
|
|
.BI D nnnnnn
|
|
(for directories)
|
|
or
|
|
.BI F nnnnnn
|
|
(for files);
|
|
a key file
|
|
.B _CONFORM.MAP
|
|
is created in the root
|
|
directory to ease the reverse process.
|
|
.PP
|
|
If the
|
|
.B -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 interpreted by
|
|
.IR 9660srv .
|
|
.PP
|
|
If the
|
|
.B -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
|
|
.I 9660srv
|
|
as well as most versions of Windows
|
|
and many Unix clones.
|
|
The characters
|
|
.BR * ,
|
|
.BR : ,
|
|
.BR ; ,
|
|
.BR ? ,
|
|
and
|
|
.B \e
|
|
are allowed in Plan 9 file names but not in Joliet file names;
|
|
non-conforming file names are translated
|
|
and a
|
|
.B _CONFORM.MAP
|
|
file written
|
|
as in the case of the
|
|
.B -c
|
|
option.
|
|
.PP
|
|
If the
|
|
.B -r
|
|
flag is given, Rock Ridge extensions are written in the
|
|
format of the system use sharing protocol;
|
|
this format provides Posix-style file metadata and is
|
|
common on Unix platforms.
|
|
.PP
|
|
The options
|
|
.BR -c ,
|
|
.BR -9 ,
|
|
.BR -j ,
|
|
and
|
|
.B -r
|
|
may be mixed freely with the exception that
|
|
.B -9
|
|
and
|
|
.B -r
|
|
are mutually exclusive.
|
|
.PP
|
|
The
|
|
.B -v
|
|
flag sets the volume title;
|
|
if unspecified, the base name of
|
|
.I proto
|
|
is used.
|
|
.PP
|
|
The
|
|
.B -:
|
|
flag causes
|
|
.B mk9660
|
|
to replace colons in scanned file names with spaces;
|
|
this is the inverse of the map applied by
|
|
.IR dossrv (4)
|
|
and is useful for writing Joliet CDs containing data
|
|
from FAT file systems.
|
|
.PP
|
|
The
|
|
.B -b
|
|
option creates a bootable CD.
|
|
Bootable CDs contain pointers to floppy images which are
|
|
loaded and booted by the BIOS.
|
|
.I 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
|
|
.I proto
|
|
file already:
|
|
the
|
|
.B -b
|
|
option just creates a pointer to it.
|
|
.PP
|
|
The
|
|
.B -B
|
|
option is similar to
|
|
.B -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.
|
|
.PP
|
|
In addition to
|
|
.B -b
|
|
and
|
|
.B -B
|
|
a boot entry for UEFI systems can be created with the
|
|
.B -E
|
|
option and with
|
|
.I bootfile
|
|
pointing to a FAT image containing the contents of
|
|
the efi system partition.
|
|
.PP
|
|
The
|
|
.B -D
|
|
flag creates immense amounts of debugging output
|
|
on standard error.
|
|
.PP
|
|
.I Dump9660
|
|
is similar in specification to
|
|
.I mk9660
|
|
but creates and updates backup CD images in the style of
|
|
the
|
|
.I dump
|
|
file system
|
|
(see
|
|
.IR 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.
|
|
.PP
|
|
The
|
|
.B -n
|
|
option specifies a time (in seconds since January 1, 1970)
|
|
to be used for naming the dump directory.
|
|
.PP
|
|
The
|
|
.B -m
|
|
option specifies a maximum size for the image;
|
|
if a backup would cause the image to grow larger than
|
|
.IR maxsize ,
|
|
it will not be written, and
|
|
.I dump9660
|
|
will exit with a non-empty status.
|
|
