"data" causes full speed to start when superblock and directory entries are
written and writing of file content blocks begins.
.TP
\fB-dvd_obs\fR "default"|"32k"|"64k"
Linux specific:
Set the number of bytes to be transmitted with each write operation to DVD
or BD media. A number of 64 KB may improve throughput with bus systems which
show latency problems. The default depends on media type, on option
-stream_recording , and on compile time options.
.TP
\fB-stdio_sync\fR "on"|"off"|number
Set the number of bytes after which to force output to stdio: pseudo drives.
This forcing keeps the memory from being clogged with lots of
pending data for slow devices. Default "on" is the same as "16m".
Forced output can be disabled by "off".
.TP
\fB\-dummy\fR "on"|"off"
If "on" then simulate burning or refuse with FAILURE event if
no simulation is possible, do neither blank nor format.

Not original mkisofs options are --quoted_path_list (see -quoted_path_list),
isolinux_mbr= (see -boot_image isolinux isohybrid=),
--hardlinks (see -hardlinks "on") --acl (see -acl "on"),
--xattr (see -xattr "on").
Not original mkisofs options are --quoted_path_list , --hardlinks , --acl ,
--xattr , --md5 , --stdio_sync . They work like the xorriso options with the
same name and hardcoded argument "on", e.g. -acl "on".
Explicit arguments are expected by --stdio_sync and --scdbackup_tag.
.br
Quite special is isolinux_mbr= (see -boot_image isolinux isohybrid=).
.br
Personalites "\fBxorrisofs\fR", "\fBgenisoimage\fR", and "\fBgenisofs\fR"
are aliases for "mkisofs".
