# help support his development of this tutorial. Another good place
# to learn from is test.pl in the Gtk/samples directory included with
# Gtk-Perl. A good reference can be found at
# http://projects.prosa.it/gtkperl/reference.html
# If you want gBootRoot to do it's stuff somewhere else, change the
# value for $tmp1.

# CHANGES
#
# 1.2.14 - 10/24/2001
# * Append field in the ABS now saves state for non-root users.
# Before it only remembered state if lilo.conf could
# actually be read, ofcourse, this wasn't an option for
# non-root users. The beginnings of non-root boot and root_fs
# creation capabilities have been put into place, but haven't
# been fully implemented. The end result of this is that
# directories created in $tmp are now static for non-root
# users and now use the userid number to keep track of
# different non-root users.
# * The author of swim came out with a new version he now calls
# dswim. This means Debian System Wide Information Manager,
# but the "d" could also stand for different. Changes have
# been made to make_debian to facilitate this much more stable
# version of swim, and better non-installed package checks
# have been implemented in make_debian.
# * The control dependencies have been vastly improved, and
# reflect the change from swim to dswim. Yard_chrooted_tests
# is now put in a gbootroot specific directory since it is
# unique to gbootroot.
# * The lastest user-mode-linux is included: 2.4.12
# * Updated the documentation, and it includes a better
# explanation in step 7 for "How can I test gBootRoot?"
# * Added checks for the existence of ash, lilo, bzip2 and file
# for the 2 disk compression method.
#
# 1.2.13 - 09/28/2001
# * Renamed "lilo" Boot method to "2 disk compression."
# * Added three new entry fields and one radio button to manage
# kernel modules, and made important changes to the 2 disk
# compression code.
# * Advanced Section is now Advanced Boot Section (ABS).
# * Properly handles two different block devices with two
# different sizes. Tested on /dev/fd?.
# * Advanced Root Section (ARS) added. Includes root device and
# size, root filesystem name with Save or Save As, filesystem
# size, gzip/bzip2/none compression, user-mode-linux kernel
# selection, Root Method and optional associated Template.
# * Yard Incorporation Tasks closed: 19556, 22668, 22496.
# * Yard Method added to ARS which generates the new well
# featured Yard Box.
# * Yard Box includes alterable staging behavior for root
# filesystem creation, template text search, adjustable
# stripping behavior, editable filesystem and replacements,
# $PATH appending, testing choices, Save and Save As.
# * Seamlessly integrated Verbosity Box and slider bar
# to control the verbosity level added to the main box.
# * Several bug fixes and enhancements to the original Yard
# scripts, including a choice of stripping features for
# libraries, binaries, modules with corresponding sizing
# checks, link -> file is now literal, unneccessary situations
# for ../ x path_length removed, testing improvements.
# * Localized directories provided for users under
# $HOME/.gbootroot
# * Wrote make_debian to automate the creation of a Debian
# template for the Yard Method. This spawned the
# make-debian-x11 add-on which is simply the make_debian
# script with easily made user modifications.
# * UML button added to ARS. UML (user-mode-linux) Box
# provides a testing bed for root filesystems. Previous
# Options are remembered to save typing, Abort button
# provides excellent process clean-up.
# * Wrote an automated package creation script which can
# be modified for other packages. This script can be found
# in CVS.
# * Added user definable resources file "gbootrootrc" for Gtk.
# * Bugs closed: 422436, 225252
#
# 1.2.2 - 09/03/2000
# * Development is now at sourceforge.net/projects/gbootroot.
# * Cristian Ionescu-Idbohrn 'cretzu' added as developer
# 08/13/2000.
# * Advanced Section GUI added.
# * Stripping (new) is now the default behavior. Stripping
# options are in AS.
# * Cretzu's gdkbirdaao() " Guess Default Kernel Boot Image
# Root Device And Append Options" is incorporated both in
# beginner section and AS.
# * Cameron Caffee <Cameron_C_Caffee@AtlanticMutual.com> sends
# detailed reports and helps with testing. This leads to
# the discovery of the need for stripping, as well as a
# version check being incorporated into the program.
# * Option for additional devices in boot disk added to AS.
# * 'Changed' signal replaces 'activate' in entry widgets.
# * Hard wired coding changes in initrd_heredoc();
# development drive can be different than boot drive;
# added as an option to AS.
# * Step increment changed for device size spinner button.
# * New documentation and grammar corrections.
# * Bugs closed: 111579, 112555, 112949, 111580, 11636, 12073,
# 12215, 13385, 13453, 13455.
#
# 1.0.3 - 08.09.2000
# * Tmp and mnt are now created on the fly,
# along with a new error function for mkdir(),
# Gtk clean-up for this, and clean-up by signal handler
# which should please Perlish and helpful Cristian.
#
# 1.0.2 - 08.06.2000
# * Changed logic slightly in submit() with returns rather
# than a scalar to resolve a minor bug caused by some
# changes in the previous version.
#
# 1.0.1 - 08.05.2000
# * Zas provided a correction for a Perl 5.6 error complaint.
# * Zas found some unecessary GDK lines causing some Gtk
# warnings; these were commented out.
# * Cristian Ionescu-Idbohrn found a bug caused by putting
# the Kernel or RootImage below the mount point. An error
# check and error dialog were added.
#
# 1.0.0 - 08.02.2000
# * First public release

# How the Boot/Root set is constructed for the 2 disk compression method:
#
# 1. submit() start the process.
# 2. kernel_modules() sets the $kernel_version.
# 3. lilo() is called.
# 4. $ok determines what functions should be called for creating the
# Boot disk.
# 5. If initrd hasn't been created yet then initrd is called, and then
# mtab(0=Boot) .. otherwise only mtab is called. If initrd is called,
# then it in turn calls initrd_size to check the size of everything going
# into the initrd, so that the initrd can be made as small as possible.
# 6. mtab determines which dialog to present to the user and then calls
# mtab_window with the numeric value determing whether to make a Boot or
# Root disk. 0=Boot 1=Root
# 7. mtab_window (prompts the user) and then calls mtab_check.
# 8. mtab_check checks whether the device is already mounted or not, and will
# keep prompting the user until either the device is umounted or a disk is
# inserted. Then it will mke2fs the block device and then it will call
# lilo_put_it_together if 0, or device2() if 1.
# 9. lilo_put_it_together puts together the initrd and necessary things to get
# lilo to work properly, and then runs lilo if the device is bootable.
# If the devel device is not the same as the boot device lilo will be
# skipped. Then mtab(1) is called.
#10. The filesystem for the Root device is made, and then device2 is called
# to copy over the root filesystem.
# My own creation - the roots touch the ground if three lines are added.

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 presently has only one Boot Method choice: "2 disk compression."
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 a 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.
