Fixed a bug which causes lock-ups during seconf fs creation with

EXPECT, and a bug where .options wasn't being written to disk or the
path was being altered when a variable was being altered.  This also
gets things trim and ready with the coolest discovery being that a
nested kernel can run on the host and in it's nest.  I'll be testing
other nested levels to discover how far this can go and be
incorporated in one package which is nice.

 ------------------
 
+Updated to 2.4.19-45um and the latest uml tools 20021103.
+
+Added a nested package, gbootroot-nest1 to allow gbootroot to have
+full functionality under uml.
+
+Wrote and added a C program skas-or-tt to automatically add the proper
+mode={skas,tt} to the commandline.  This means compilation will be
+optimized, and things won't lock up when using gbootroot-nest1 with a
+uml running on top of a host kernel without the skas patch.
+
 The MTD Emulator doesn't work as nicely as before.  Blkmtd seems
 mostly broken, and mtdram needs more careful tweaking for total size,
 though mtdram definitely still works.  This is due to changes in uml
@@ -13,17 +23,28 @@ this change exists with the new port-helper because wasn't the case
 before.  Also, added path for user-mode-linux/usr/bin to find the
 other tools.
 
+The Makefile has been altered quite a bit, and wgets necessary
+sources, unconventional but very nice in keeping up with jdike's
+latest patch.  You can now live quite happily out of the source
+directory.
+
+Added the templates for Initrd and root_fs_helper and the
+corresponding replacements that are also used by the source package.
+
+Updated the documentation, and the README found in the source packages
+is now available in the normal packages.
+
 The biggest change is the command-line interface with the yard root
 method.  Now distribute your template and let others easily recreate
 your root_fs without entering the gui by running "gbootroot --template
 your_template" and this is a nice way to manage a distribution you are
-developing.  This all means the source packages are completely
+developing.  This also means that source packages are completely
 automated now, and vastly improved, which is quite awesome.
 
 When root_fs_helper was running with the newer Expect.pm, and
 consequentially the newer uml kernel it became necessary to get out
 when the kernel shuts down with a last function right when it says
-"Power down."
+"Power down" or "bd.*module cleaned up."
 
 Checks for the proper version for newer libc6 linkers.  Hopefully,
 should work properly with libc6 > 2.3.1, too.

 Should the host kernel have the skas patch applied?
