Version 1.1 is now attached to the first post in this thread with the following changes:
-Added a third method to add extensions to the remaster (original 2 methods were to include extensions outside the initrd or to include them inside the initrd). The new third option, "Extract TCZ in to initrd", is to install extensions by copying the extension files into the initrd by mounting the extension and copying all extension files to the extracted initrd filesystem, so that the resulting remaster doesn't have extensions to load at boot as the extensions are integrated in to the initrd. Extensions are extracted in to the initrd in the correct dependency order, and if the TCZ has a /usr/local/tce.installed/appname startup script the program supports 3 options on how to handle these: 1: Run the TCZ startup scripts in a chroot environment during the remaster, 2: Add TCZ startup scripts to the /opt/bootlocal.sh file, or 3: Ignore startup scripts.
