I'll look into this, thanks. Hoping we can just use a glibc agnostic build, not sure if that will bloat binary or have other consequences.

Perhaps we need to ensure CGO_ENABLED=0.

Perhaps we need to ensure CGO_ENABLED=0.

Ya my early research suggests this too. I haven't had time to prove it out though 😅

fix: CGO_ENABLED=0 for statically-linked builds (#1102)
ada40a6 
Removes the dependency on native c-libs for more portability.

This is already done in the docker builds, updates were only needed for
bins. Tested this locally by mounting it into an old Ubuntu and it
resolved the issue.

Fixes: #878
