# 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.
my $tmp1 = "/tmp";              # tmp should be default - Cristian

# CHANGES
#
#       1.0.3b - 08.24.2000 cretzu
#               * replaced 35 occurences of "$tmp/verbose" with the new
#                 variable $verbosefn
#               * some lines contained > 1 rmdir statement separated by ','
#                 and not ';'; splitted those
#
#       1.0.3a - 08.23.2000 cretzu
#               * corrected bugs in norm_root_device (returned always 'hda1')
#                 a) now closes LIL
#                 b) chomps all lines in one go
#                 c) the 'default' value is just a label, not a dev
#                 d) sane regexp magic
#                 e) "there's one more bug(tm)": does not cope with multiple
#                    root device occurences (which might be present in each
#                    'image=' block
#
#       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 $version written by Jonathan Rosenbaum $date GNU GPL
email:mttrader\@access.mountain.net
site -> http://the.netpedia.net/gBootRoot.html

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:

gBootRoot is similar to BootRoot, but it is more efficient
and powerful.  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".

There are 5 rows.  The boot method column has only one choice "lilo."
Clicking on the menu on the right selects the 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.
If you choose the compressed filesystem with the file selector the program
should automatically detect the compression used, otherwise, click on the
appropriate radio button to choose either gzip or bzip2 compression.

Little things you may want to know:

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