That's really not nice. It's a security feature to avoid file corruption and tampering. But you could disable the checks in if nothing helps:
- https://github.com/LordOfDragons/dragen ... e.cpp#L548
- https://github.com/LordOfDragons/dragen ... n.cpp#L390
You would need to disable the entire if-blocks there to avoid the file based exception.

Re: NixOS Package
Is there a way I could generate the manifest files separate from the main build step after the modules have been patched?

Re: NixOS Package
The manifest files are XML files. You can use an XML library to load, edit and save them. Most probably simpler would be using an XSLT processor to alter a specific tag content. "xsltproc" is the usual command line tool to do this.

Re: NixOS Package
So is it now all working as expected? Anything I should upstream or not?

I wasn't planning on using it much, so the extra effort to get it working wasn't worth it.

Re: NixOS Package
I see. I guess NixOS is quite special in the way packaging works to cause that many troubles.gale_username wrote: ↑Wed Oct 30, 2024 10:40 pm I wasn't planning on using it much, so the extra effort to get it working wasn't worth it.
