Hi,
I am trying to create a windows installer that has the virtio drivers builtin, for fully automatic and unattended installation.
In particular I am trying to inject the driver vioscsi into boot.wim and then install.wim
I can unpack and repack the iso.
I can inject actual driver files into the wim files
I think all that is left is to create the registery keys in the registery hive files,
The keys that need to be created, if I had a "reg add" command
But I would like to create cleaner, more reusable shell function for adding each node/key/values
Here is an untested attempt of ths reg_add shellfunction
So we might then have a single shell function to just add vioscsi to a specified hive
I have created a shell function which can inject drivers files to all "image indexes" in the wim file
Shell function not fully tested
then I repack the iso
create_windows_iso /mnt/iso/template/win10-repack/iso-master /mnt/iso/template/iso/Win10_22H2_EnglishInternational_x64_unattended-2025-1-10.iso
shell function not fully tested
And now putting it all together
