# Perhaps you are wondering where to learn how to program with Gtk-Perl?
# There is an excellent tutorial by Stephen Wilhelm at
# http://personal.riverusers.com/~swilhelm/perlgtk/.  Please
# 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.

# If you want gBootRoot to do it's stuff somewhere else, change the
# value for $tmp1.

# CHANGES
#
#       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

gBootRoot is a Gtk+/Perl program useful for both beginners and advanced
GNU/Linux users.  It makes the construction/development of emergency and
mini distributions simple.

- A GNU/Linux user can easily create an emergency Boot/Root set.
  There are a multitude of pre-existing compressed filesystems readily
  available.  Please check the gBootRoot FAQ at the gBootRoot site
  listed above.

** If you are a developer please send me links to Kernel/Filesystems
   which I can share with users of gBootRoot.

- A developer creating a mini distribution can concentrate his efforts
  on perfecting the filesystem, and then he can use gBootRoot to
  quickly create a Boot/Root set to run tests.

- Disk sets allow for more space to include interesting and necessary
  things.  The size of the Kernel is increasing every day making sets
  advantageous.


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 has only one choice "lilo."  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.

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 is 1722 which works fine with 1440 floppy drives. Click on the 
appropriate radio button to choose either gzip or bzip2 compression if the 
program doesn't automatically detect it.

Advanced Section:

"Stripping"  On by default for libraries and binaries.  The stripping 
behavior for libraries may be changed by clicking on the right mouse button 
to change from --strip-debug to --strip-all.

"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.

Little things you may want to know:

* gBootRoot requires ash for initrd.  Ash is a feather weight version of Bash.
