:B~ Customizing the binary image
1~customizing-binary Customizing the binary image
2~ Bootloaders
live-build uses /{syslinux}/ and some of its derivatives (depending on the
image type) as bootloaders by default. They can be easily customized to suit
your needs.
In order to use a full theme, copy #{/usr/share/live/build/bootloaders}#
into #{config/bootloaders}# and edit the files in there. If you do not want
to bother modifying all supported bootloader configurations, only providing
a local customized copy of one of the bootloaders, e.g. *{isolinux}* in
#{config/bootloaders/isolinux}# is enough too, depending on your use case.
When modifying one of the default themes, if you want to use a personalized
background image that will be displayed together with the boot menu, add a
splash.png picture of 640x480 pixels. Then, remove the splash.svg file.
There are many possibilities when it comes to making changes. For instance,
syslinux derivatives are configured by default with a timeout of 0 (zero)
which means that they will pause indefinitely at their splash screen until
you press a key.
To modify the boot timeout of a default #{iso-hybrid}# image just edit a
default *{isolinux.cfg}* file specifying the timeout in units of 1/10
seconds. A modified *{isolinux.cfg}* to boot after five seconds would be
similar to this:
code{
include menu.cfg
default vesamenu.c32
prompt 0
timeout 50
}code
2~ ISO metadata
When creating an ISO9660 binary image, you can use the following options to
add various textual metadata for your image. This can help you easily
identify the version or configuration of an image without booting it.
_* #{LB_ISO_APPLICATION/--iso-application NAME}#: This should describe the
application that will be on the image. The maximum length for this field is
128 characters.
_* #{LB_ISO_PREPARER/--iso-preparer NAME}#: This should describe the
preparer of the image, usually with some contact details. The default for
this option is the live-build version you are using, which may help with
debugging later. The maximum length for this field is 128 characters.
_* #{LB_ISO_PUBLISHER/--iso-publisher NAME}#: This should describe the
publisher of the image, usually with some contact details. The maximum
length for this field is 128 characters.
_* #{LB_ISO_VOLUME/--iso-volume NAME}#: This should specify the volume ID of
the image. This is used as a user-visible label on some platforms such as
Windows and Apple Mac OS. The maximum length for this field is 32
characters.
