Program:  gBootRoot  pronounced "bOOtrOOt"
License:  GNU General Public License

The Makefile included with this source package doesn't attempt
to figure out whether your system has the proper requirements.
It may seem like a great idea to have a configure script, but
these things can fail, besides gbootroot is a program designed for users
who intend to build distributions and boot disks, so understanding what
things are required to get gbootroot to work completely can be quite 
beneficial.  At the very least, do a "make", and try gbootroot because the 
program will tell you what things are missing - hopefully nothing - and then 
you can refer to this README for help.

Out of the box this program works with the i386 architecture, for other 
architectures genext2fs and user-mode-linux will need to be compiled if
full functionality is desired.  Eventually, the Advanced Kernel Section in
this program will be able to help with the uml compile.


Perl Modules:
#############

Gtk-Perl
--------

Version 0.7002 or greater.
http://freshmeat.net/projects/gtk-perl


Binaries:
#########  

Genext2fs
---------
genext2fs/genext2fs ( included and already compiled for i386 )
cd genext2fs; make  ( other architectures )

User-Mode-Linux
---------------
user-mode-linux/usr/bin/{linux,uml_*}     ( included and already compiled 
	                                                         for i386 )
user-mode-linux/usr/lib/uml/{modules*tar} ( included and already compiled 
                                                                 for i386 )
user-mode-linux/usr/lib/uml/config        ( kernel .config defaults )

If you use a different architecture you will need to read 
http://user-mode-linux.sourceforge.net/arch-port.html.  

Here the basic instructions to compile uml stuff:

Get kernel sources from www.kernel.org, and then a matching uml-patch from 
http://sourceforge.net/project/showfiles.php?group_id=429.  If you want to 
match the kernel version used by gbootroot check Changes to find out which 
version of uml if being used.  You may want to use config as your .config at 
the base of the sources as a starting point, and then modify the kernel 
configuration in whatever way required.  There are good instructions on how to
compile a uml kernel at http://user-mode-linux.sourceforge.net/UserModeLinux-HOWTO-2.html.  
Then put the uml kernel in the directory cited above and call it linux; you can
put the modules in a Replacements directory later on (see FAQ).  

The helper uml_* tools need to be checked out from cvs and compiled with make:

(Instructions for cvs at http://sourceforge.net/cvs/?group_id=429.)
cvs -d:pserver:anonymous@cvs.user-mode-linux.sourceforge.net:/cvsroot/user-mode-linux login
cvs -z3 -d:pserver:anonymous@cvs.user-mode-linux.sourceforge.net:/cvsroot/user-mode-linux co tools

cd tools/mconsole; make;
cd ../uml_net; make; chown 0:0 uml_net; chmod 4755 uml_net;
cd ../uml_router; make;
cd ../uml_moo; make;

Put the uml kernel in the directory cited above with the same names.  When
you run gbootroot's Makefile everything will be put in the proper places.

Note:  Please send the user-mode-linux-devel and gbootroot-devel lists your 
experiences if you successfully get another architecture working so they can 
be shared with the community.


Boot Methods:
#############

2 disk compression
------------------

This method will tell you when any of these utilities are missing:

ash  lilo  bzip2  file


Root Methods:
#############

Yard
----

Watch the verbosity box, it will be obvious when a required command is missing.
Make sure you have this file installed on your system:

Important Configurations:
#########################

"chmod 4755 /usr/bin/uml_net" so normal users can have network capabilities.
