Dear Maintainer, after taking another pass at this issue, somebody pointed out that the Debian patches are indeed responsible for this behaviour: https://salsa.debian.org/go-team/packages/prometheus-node-exporter/-/blob/debian/sid/debian/patches/0001-Debian-defaults.patch?ref_type=heads
These changes were migrated as part of report #908811. Now I wonder, are these overridden defaults still necessary today? The information scraped by this service should be cached by the kernel anyway, so waking up disks should not be the issue (anymore)? Nevertheless, these changed defaults are not documented except within the source code itself, so I would advise providing a "README.debian", as usual practice for these modifications. Looking forward to your feedback, simonmicro
