-r, -rational-rock Generate rationalized Rock Ridge directors -R, -rock Generate Rock Ridge directory information
-N, -omit-version-number Omit version number from ISO9660 filename (violates ISO9660)

-d Omit trailing period from files that do not have a period.
This violates the ISO9660 standard, but it happens to work on
many systems. Use with caution.
-D Do not use deep directory relocation, and instead just pack them
in the way we see them.
This violates the ISO9660 standard, but it happens to work on
many systems. Use with caution.
-N Omit version numbers from ISO9660 file names.
This violates the ISO9660 standard, but no one really uses the
version numbers anyway. Use with caution.
-C last_sess_start,next_sess_start
-M device
Specifies path to existing iso9660 image to be merged.
If the -C option is used in conjunction with the -M option, mkisofs will create a filesystem image that is intended to be a continuation of the previous session. If the -C option is used without the -M option, mkisofs will create a filesystem image that is intended to be used for a second session on a CDextra. This is a multi session CD that holds audio data in the first session and a ISO9660 filesystem in the second session.
-root dir
Moves all files and directories into dir in the image. This is
essentially the same as using -graft-points and adding dir in
front of every pathspec, but is easier to use.
dir may actually be several levels deep. It is created with the same permissions as other graft points.
-graft-points
Allow to use graft points for filenames. If this option is used,
all filenames are checked for graft points. The filename is
divided at the first unescaped equal sign. All occurrences of
'\\' and '=' characters must be escaped with '\\' if
-graft-points has been specified.
If the option -graft-points has been specified, it is possible to graft the paths at points other than the root directory, and it is possible to graft files or directories onto the cdrom image with names different than what they have in the source filesystem. This is easiest to illustrate with a couple of examples. Let's start by assuming that a local file ../old.lis exists, and you wish to include it in the cdrom image.
foo/bar/=../old.lis
will include the file old.lis in the cdrom image at /foo/bar/old.lis, while
foo/bar/xxx=../old.lis
will include the file old.lis in the cdrom image at /foo/bar/xxx. The same sort of syntax can be used with directories as well. mkisofs will create any directories required such that the graft points exist on the cdrom image - the directories do not need to appear in one of the paths. By default, any directories that are created on the fly like this will have permissions 0555 and appear to be owned by the person running mkisofs. If you wish other permissions or owners of the inter- mediate directories, see -uid, -gid, -dir-mode, -file-mode and -new-dir-mode.
Excerpted from mkisofs/README.hide
This document attempts to show how to hide files from being seen by an operating system accessing a CD as an ISO9660/Rock Ridge, Joliet or HFS CD. It also highlights some of the limitations …
Note: this document is about the various -hide options - not be confused with the -hidden options.
The various -hide options actually exclude the relevant directory entry from the directory tree. Therefore, it is not possible to access a file or directory that has be hidden with the -hide option when the ISO9600/Rock Ridge directory is mounted - because the directory entry does not exist on the CD (but the file data does). You would probably be able to access this file or directory when mounted as a Joliet or HFS CD (depending on other options used). Similarly, a directory entry hidden with the -hide-joliet option will not be accessible when mounted as an Joliet CD. Similarly for -hide-hfs etc.
If the file name to be hidden is a directory, then the directory and all its contents are hidden.
The main use of the hide options is on a multi platform (hybrid CD) to hide various files/directories that are operating system specific from been seen on the CD when mounted on another OS. i.e. You may want to hide Macintosh executables from being seen when the CD is mounted as a Joliet CD on a PC etc.
The -hidden options set the 'EXISTENCE' bit in the directory entry which means the file or directory will be invisible - unless some special option is used to mount or view the CD - Linux has the 'unhide' mount option to make these files visible. i.e. the directory entry exists on the CD.
Add the hidden (existence) ISO9660 directory attribute for glob. This attribute will prevent glob from being listed on DOS based systems if the /A flag is not used for the listing. glob is a shell wild-card-style pattern that must match any part of the filename or path. In order to match a directory name, make sure the pathname does not include a trailing '/' character. Multiple globs may be hidden.
Utilities to create compressed CD-ROM filesystems.
First create a directory tree containing compressed files:
mkzftree input_dir compressed_dir
mkzftree will not overwrite an existing directory; you may want to "rm -rf" the directory tree if you are doing this from a script:
Second, invoke the patched mkisofs with the -z option:
mkisofs -z -R [other options] -o compressed.iso compressed_dir
-z, -transparent-compression
Enable transparent compression of files
-R, -rock Generate Rock Ridge directory information
Note:
you *must* enable RockRidge (-R or -r) since this is an extensions to the RockRidge specification. Without RockRidge, -z will have no effect.
for files that you want to be readable under all circumstances (files involved in booting, or README files), you can simply put them in a separate tree and not run mkzftree on that tree.
mkzftree will not compress files that end up larger when compressed;
you can specify -p and a parallelism (e.g. -p4) to allow files (up to the number specified) to compress in parallel. This might speed things up if you are not completely I/O bound. The default is -p0.
ISOF=../disk1.iso dirdel $tmp_f.Z mkzftree . $tmp_f.Z mkisofs -r -N -L -d -D -J -f -o $ISOF -z -R -graft-points $tmp_f.Z
mkisofs
-z Generate special RRIP records for transparently compressed
files. This is only of use and interest for hosts that support
transparent decompression, such as Linux 2.4.14 or later. You
must specify the -R or -r options to enable RockRidge, and gen-
erate compressed files using the mkzftree utility before running
mkisofs.
