It's my third attempt to make my regular Linux desktop less disk-chatty. This is a huge issue for btrfs and for COW FS in general, because they have massive write amplification for small and frequent writes (38,7 TB written to my idle desktop SSD in 2 years).

If you're interested, here are my findings this time so far:

    - workrave: 60 second stat sync https://github.com/rcaelers/workrave/pull/717
    - kde klipper: saves to disk on every copy, even if permanent storage is disabled https://bugs.kde.org/show_bug.cgi?id=501030
    - kde plasmashell: saves qt shader cache each time notification popup disappears https://bugs.kde.org/show_bug.cgi?id=523805
    - bitwarden firefox extension: tries to connect to desktop application every 10 seconds, writes about every failure to browser's WebStorage 14+ KB https://github.com/bitwarden/clients/issues/22192
    - firefox datareporting/glean: very chatty .mozilla/firefox/xxx/datareporting/glean/db/data.safe
    - ipfs: writes every received DHT announce to disk, 20 GB in 3 hours https://discuss.ipfs.tech/t/constant-writes-to-datastore-log/20316
    - mailcow: redis saves data every 5 minutes https://github.com/mailcow/mailcow-dockerized/pull/7405

I am not again binary logs, or logs in a database. It's just yet another time I deal with good ideas implemented horribly, horribly badly when it comes to systemd.
