# DNF Count Me support

Classic DNF based operating systems can use the [DNF Count Me feature][countme]
|
||
|
|
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
|
||
|
|
```
