The diversity of user systems creates a significant hurdle for eBPF program portability. While we might wish for universally updated environments, reality includes legacy OS versions and kernels missing features like BTF support. For developers, particularly in open source where user environments are unknown and uncontrolled, this variability makes it challenging to guarantee their eBPF programs will run correctly. This reliability issue is a key factor in whether users adopt an eBPF tool. Therefore, the essential problem is finding ways to make eBPF programs truly portable across these varied configurations.
