DNF Count Me support

  1. Disabling DNF Count Me on a system

Classic DNF based operating systems can use the DNF Count Me feature to anonymously report how long a system has been running without impacting the user privacy. This is implemented as an additional countme variable added to requests made to fetch RPM repository metadata. On those systems, this value is added randomly to requests made automatically via the dnf-makecache.timer or via explicit calls to dnf update or dnf install.

However, this does not work for rpm-ostree based systems as in the default case (no package overlayed on top of the base commit), rpm-ostree will not fetch any RPM repository metadata at all.

Thus rpm-ostree includes a distinct timer (rpm-ostree-countme.timer), triggered weekly, that implement the DNF Count Me functionality in a standalone way.

Disabling DNF Count Me on a system

To disable this feature, you need to update the Count Me option in all RPM repository configuration files:

sed -i 's/countme=1/countme=0/g' /etc/yum.repos.d/*.repo

You should also stop and disable the rpm-ostree-countme.timer:

$ systemctl disable --now rpm-ostree-countme.timer
