According to this blurb “zeitgeist-daemon is a daemon which keeps track of activities on your system (file usage, browser history, calendar events, etc.) and logs them into a central database. It does not only create a chronologic register, but also supports tagging and can establish relationships between activities.”
I suspect that those deleted files will grow large again since they log activity. If you don’t like it keeping track of that stuff, why not disable or even uninstall it?
Point is, I was never aware of the existence of the mysterious Zeitgeist daemon until today. Before disabling or removing something I first try to understand a little of its history and purpose.
Seems odd that a privacy distro like PureOS would have something like this enabled by default.
It does not appear to be installed on my Librem 5, so probably it is not installed by default in that environment.
That then raises the question as to whether it was installed by default in your environment or whether something that you installed pulled it in i.e. as a dependency, in which case it could be a problem to uninstall it. If you have a Live Boot USB handy, you might want to see whether it is installed by default.
So I have no idea how zeitgeist made it onto my system at this point. I’m guessing most people should be able to remove it from their system without issue.
Random anecdote, my Librem 5 and LIbrem 14 are running Byznatium, but do not appear to have a .local/share/zeitgeist folder. I do not have any recollection of intentionally removing this package, nor do I recall hearing its name.
Maybe zeitgeist was a dependency for something that you installed in the past?
