====== Introduction ======

[[dynamic_root_filesystem_remastering|Dynamic remastering]] is about assembling 1+ initrd payload files (CPIO.GZ archives for initramfs; herein referred to as CGZs) to allow one to upgrade the core.gz without a full repacking.  Dynamic MultiMaster takes this one step further to create a set of modular CGZs that allow component swap/addition from the boot loader without repeating files.

====== Prerequisites ======
  * An understanding of dynamic remastering

====== Overview ======
  * Examine what extensions you would like in each target boot
  * Fetch extensions their .dep files, and dependent extentions & .dep files.
    * .tree files help to broadly examine all dependencies for an extension
  * Determine how to modularly group the extensions into CGZs to eliminate duplicated extensions.

====== Details ======
  * Extensions and their .deps should be located in [boot-tce-dir]/optional/.  As of 4.7.5, that becomes /tmp/builtin/optional/ but was in /opt/tce/ before version 4.2.
  * Multiple CGZs function to overwrite files (and directory permissions).
  * An onboot.lst in [boot-tce-dir] is needed to load files on boot.  As of 4.7.5, that becomes /tmp/builtin/onboot.lst

====== Examples ======
===== TinyCore-like with XVesa, Xfb or X.Org =====
This is one of the quickest modularization examples.

==== tcxdep.cgz ====
The extensions TinyCore uses other than any X-specifics
  * fltk-1.1.10.tcz flwm_topside.tcz wbar.tcz Xlibs.tcz Xprogs.tcz 
    * fltk-1.1.10.tcz and Xlibs.tcz are the dependencies for the others

==== tcxv.cgz ====
  * Xvesa.tcz

==== tcxfb.cgz ====
  * Xfbdev.tcz

==== tcxorgdep.cgz ====
Break out some dependencies since they are shared with other extensions since we may want those but not X.org
  * expat2.tcz fontconfig.tcz pixman.tcz Xorg-7.6-lib.tcz

==== tcxorgdrv.cgz ====
This can be trimmed as needed, based on desired hardware.

===== VMware View Client =====
VMware's recent release of its full View client is of interest to some since TC could be lighter than other distros.
  * tcxdep.cgz, tcxv.cgz, and tcxorgdep.cgz as above.  This is an excellent example of why I removed the extensions in tcxorgdep.cgz to another CGZ.
