When logging into a Debian 10 instance, one is greeted with some system information including:
The meters always display
0.0%, irrespective of the actual usage. These numbers are generated in /etc/update-motd.d/50-scw by awk scripts that incorrectly parse parse the output offree -m.This pull request fixes those scripts. It has been tested on a Debian 10 Scaleway instance and on an Ubuntu 18.04 desktop (tested the parsing of
