For example the script try-to-fix-low-on-disk-space doesn't send notifications. This is because the echo NOTIFY statements are not sent to systemd's journal.
How to reproduce:
- Check free disk space:
sudo btrfs filesystem usage / | grep df
- Create a huge file close to what's left on the drive:
fallocate -l 818.7GiB ~/.cache/mozilla/firefox/test
- Auditd will trigger the
try-to-fix-low-on-disk-space but no desktop notification is sent
- echo statement doesn't appear in the output of
sudo systemctl status auditd
