How to Use gBootRoot:
The most important button to familiarize yourself with is the Submit button
which starts the whole process; dialogs are presented as the process
continues asking you if you want to continue "OK" or stop "Cancel".
The first row allows you to choose a Boot Method. Clicking on the menu on
the right selects the Boot Method.
The second row allows you to select the kernel for the Boot/Root set. You
may either use the file selector button on the right hand side, or you may
type in the location on the left hand side.
The third row allows you to select the compressed filesystem you are
providing, using either of the two ways mentioned before. You may use a
pre-made root filesystem or you may create one using one of the Methods
provided in the Advanced Root Section.
The fourth row allows you to select the device you want to use. The default
device is the first floppy disk (/dev/fd0).
The fifth row allows you to choose the size of the device being used. The
default size of 1440 assumes you are using a floppy drive (Note: You may want
to experiment with 1722 which works fine with many floppy drives.), but can
be used with other sized devices like tape drives. Click on the
appropriate radio button to choose either gzip or bzip2 compression if the
program doesn't automatically detect it.
The slider bar on the right allows the output of the verbosity box to be
changed from the highest (2) to the lowest setting (1) or to be turned off (0)
or on again. At times it may be advantageous to turn off the verbosity box
since large quantities of output to this box may cause gbootroot to use too
much cpu power; however, output may still be found in the text file "verbose"
in /tmp/gbootroot_tmp'time-date'.
Advanced Boot Section:
Libraries & Binaries & Modules check boxes: Turn off and on the
stripping of symbols. The stripping behavior for libraries may be
changed by clicking on the right mouse button to change --strip-debug
to --strip-all. Binaries default to --strip-all and Modules default to
--strip-debug.
"Devel Device" If the device used for development is different than the
actual boot device, use this field to indicate that device. You will have to
run lilo -v -C brlilo.conf -r "device mount point" manually at a later time
on the actual boot device.
"Opt. Device" Add devices to the boot disk which are necessary for the
kernel to function properly. Put a space between each device. For instance,
/dev/fb0 for frame buffer devices.
"append =" Add append options to brlilo.conf. If you are using a frame
buffer device you could add something like video=matrox:vesa:402,depth:16.
"Kernel Module" Add the modules found in /lib/modules/kernel-version
which are necessary for the Boot Method to work properly. If these
modules aren't found in the modules directory it is assumed that they
either are in the kernel or they do not exist. In the case of 2 disk
compression, floppy needs to be included in the kernel or included as a
module. Kmod inserts the modules, and kmod needs to be built into the
kernel along with initrd and ramdisk."
"Kernel Version" Override the kernel version number found in the
kernel header. This will change the /lib/modules/kernel-version
directory.
System.map: When a non-running kernel is chosen it is important to
include a copy of that kernel's System.map file so that depmod can
use the correct set of kernel symbols to resolve kernel references
in each module. This can be found in the kernel's source code after
compilation.
Advanced Root Section:
"Root Device" This is the device used for the root filesystem when
constructing the Boot/Root set. You may choose a device which is different
than the Boot device, but presently only floppy devices are supported.
"Root Device Size" The size of the actual media used for the Root Device.
"Root Filename" The name give to the root filesystem when initially made
in the temporary creation location. The save button allows the creation to
be saved in the permanent default location when the Accept button is pressed.
"Filesystem Size" Root Methods make the filesystem the size which is
specified here.
"Compression" Off by default to allow user-mode-linux testing. Turn on
compression when you are ready to use a Boot Method which requires compression.
"Method" The root filesystem creation method.
"Template" The template associated with a Root Method. Not all Root Methods
have templates.
"Generate" This puts the chosen Root Method in action.
"UML" Abbreviation for user-mode-linux. This is a linux kernel which runs on
top of the host system's linux kernel and allows a you run a live root
filesystem.
"Accept" This accepts the created root filesystem if it is found in the
temporary creation directory. The UML box and the main section will now
reflect the path to this root filesystem. You can now test with the UML
button or put together a complete Boot/Root set with the Submit button.
Advanced Kernel Section:
Still in development.
Little things you may want to know:
* gBootRoot requires ash for initrd. Ash is a feather weight version of Bash.
