My laptop isn’t under my supervision most of the time. And I’d hate it if someone were to steal my SSD, or whole laptop even, when I’m not around. Is there a way to encrypt everything, but still keep the device in sleep, and unclock it without much delay. It’s a very slow laptop. So decryption on login isn’t viable, takes too long. While booting up also takes forever, so it needs to be in a “safe” state when simply logged out. Maybe a way that’s decrypt-on-demand?
I’m on Arch with KDE.
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=wheelhttps://wiki.archlinux.org/title/Systemd-homed#Creation
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.
Okay I just had a bit of freetime to test it: doesn’t work… if I log out or sleep, my home dir is still mounted. Meaning it’s as good as nothing. Looked at the plasma fix, didn’t work. I have a pretty good lead, that I need the topmost template from some wiki:
[Unit] PartOf=graphical-session.targetProblem is, where in the world should I write this? I really don’t expect you to know, but maybe I’m talking to a genius. The internet didn’t help, or I used it wrong.
The template is supposed to be something that you put in your own systemd services.
plasma-kwin_x11.serviceandplasma-kwin_wayland.serviceboth 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/startkdercshowssystemBoot = true. If it does not, runkwriteconfig6 --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
cat ~/.config/startkdercreturnssystemdBoot=true. I’m guessing you made a typo and this is correct. In this case I guess it just doesn’t work on KDE, my next idea is LUKS on /home and hibernating instead of sleeping. Or I always wanted to try a tiling window manager… hmsystemdBoot 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!
No problem, thanks for the help. Also I got news is that I don’t have to trust anyone with my laptop, I can keep it by my side after all. Still it’s a security mesure, that I didn’t solve in time. fun fact: LUKS on /home only breaks KDE. I really don’t want to give up kde tho, I put on sway, realised that I needed to memorise console commands to change my fking volumes, so no thank you. I got spoiled by sweet UIs. it’s so comfortable that everything is at one place.
Hehe, Thank you. But by the time I’m reading this I’ve already done it. Got stuck on a couple or roadblocks, but figured it out. I got scared when I didn’t “enable” the service just “start” it. I’m not safe(-ish enough). :D
edit: well not the plasma fix. wiki said if it’s a problem I need to start something, and that something should be on by default. So I didn’t do anything, maybe that’s a problem
