Introduction

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 another directory 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.

tcxorg.cgz

  • Xorg-7.6-bin.tcz Xorg-7.6.tcz Xorg-fonts.tcz

Command line

  • XVesa: initrd=core.gz,tcxdep.cgz,tcxv.cgz
  • Xfbdev: initrd=core.gz,tcxdep.cgz,tcxfb.cgz
  • X.org: initrd=core.gz,tcxdep.cgz,tcxorgdep.cgz,tcxorgdrv.cgz,tcxorg.cgz
