Yeah, to make things spicy, what we ship is a plugin, so there's limit of how static we can link. glibc stays dynamic and that's a huge limiting factor.

I've got plans to try to build on RockyLinux9 and package its glibc along with the app. Simple helloworld works, so I have a glimpse of hope that it would be possible to ship like that.

Neither of those fixes issues with system-calls not existing because the linux kernel was so old.
