Thanks @gonzalo-bulnes - Yes, packaging as RPM would likely be the ultimate best, if I get time to learn in the future. Thanks for the resources on that!
Using this command seems to be the right quick and dirty method (source):
qvm-run -p QUBE_NAME 'cat NAME_OF_FILE ' > NAME_IN_DOM0
@qubesuser1234 - I also have a 4.1.X installation, and the grub.cfg is located specifically at β/boot/efi/EFI/grub.cfgβ. You could try running the command for all three locations. But I donβt think this step should fundamentally prevent the stateless system from booting either, rather, should just boot with lower maximum Dom0 RAM available.
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
sudo grub2-mkconfig -o /boot/efi/EFI/qubes/grub.cfg
sudo grub2-mkconfig -o /boot/efi/EFI/grub.cfg
It looks like the Qubes Forum software maybe changed the quote characters in my posted script files (module-setup.sh, pass.sh, tmpfs.sh) from straight-quotes (") to curly/angled-quotes (β), because I used a different code tag than I probably should have. These malformed quote characters may have been some or all of the source of confusion and non-working file corruption.
All quotes typed into script & config files should strictly be plain straight quote characters (").
I will plan to soon repost with corrected formatting of quote characters.
In the meantime, here are the believed correct file hashes I have:
