You can get GPS systems that upload data using a SIM. Only viable if you live somewhere with cheap roaming plans. Last I checked, a local company was selling the hardware (without sim) for 200EUR. The thing I was trying to protect was 120-ish.

systemdBoot is supposed to be true, not a typo. But yeah, I don’t use plasma much so I don’t really know how to solve the issue… Sorry for that!

The template is supposed to be something that you put in your own systemd services. plasma-kwin_x11.service and plasma-kwin_wayland.service both already have it.

If I have to guess, it is probably a bug that will get fixed sometime in the future, meaning this is not a viable solution until then. Sorry for that.

Just as a last bit of troubleshooting, check if cat ~/.config/startkderc shows systemBoot = true. If it does not, run kwriteconfig6 --file startkderc --group General --key systemdBoot true. I doubt this will change much, but still worth trying.

If I get some free time, I will do some testing and let you know here

Systemd has a good guide on how to use it https://systemd.io/HOME_DIRECTORY/

And they also have a guide on migrating a traditional user home to this. Do remember to take backups if going this route https://systemd.io/CONVERTING_TO_HOMED/

I personally used the arch wiki when I set it up https://wiki.archlinux.org/title/Systemd-homed

There is not much config.

I think the command I used for my laptop was:

homectl create <name> --storage=luks --shell=/usr/bin/fish --member-of=wheel

Gnome is working on a gui for this, but it will probably be a while until that is out. I feel like it is pretty safe to use the cli for this one.

Maybe systemd-homed is the solution you are looking for. The arch wiki has a page for it. And this can be better for your use case because only your home folder needs decryption and not the whole drive.

There is this to keep in mind since you are using KDE, but can be easily fixed: https://wiki.archlinux.org/title/Systemd-homed#Home_directory_remains_active_after_logging_out_of_Plasma

Fish shell. I switched to fish ages ago, back when I didn’t know much bash scripting. Now I am just so used to it that I don’t wanna switch back. Plus it just works.

And can I have a twin sequential turbocharger for the best car of the century? “You are not gonna believe this”
