node_os_info does not update build_id #2981
Description
The collector responsible for node_os_info only appears to run a single time, I see the following metrics:
{__name__="node_os_info", build_id="23.11.20240320.f091af0", id="nixos", instance="...:9100", job="node", name="NixOS", pretty_name="NixOS 23.11 (Tapir)", version="23.11 (Tapir)", version_codename="tapir", version_id="23.11"}
{__name__="node_os_info", build_id="23.11.20240328.219951b", id="nixos", instance="...:9100", job="node", name="NixOS", pretty_name="NixOS 23.11 (Tapir)", version="23.11 (Tapir)", version_codename="tapir", version_id="23.11"}
Note that one of the build_id is from more than a week ago - however I've done several system builds on this box in that time - the newer build version only appeared after I had restarted node-exporter.
