[SOLVED]systemctl user environment

I found an issue in the environment variables read by systemd.

% systemctl --user show-environment | grep HOME
2:HOME=/
7:SYSTEMD_HOME=1
8:SYSTEMD_HOME_SUSPEND=0

which is obviously not good. Now I run:

$ systemctl --user import-environment HOME
% systemctl --user show-environment | grep HOME
2:HOME=/home/gabx

which is correct. Now, it has gone after a reboot and can't find a proper way to set it permanently. I edited a ~/.config/environment.d/10-envars.conf as suggested in the systemd/user Archwiki.
My file contains: HOME=/home/gabx, but it is not taken into account by systemd.

What is the proper way to fix across reboot the systemd HOME environment variable?

I see your point of view, and yes it maybe due to my issues with homectl. But how can I fix it?

Your using not having entries in /etc/passwd is a major problem - what does that file look like (despite the name there's no passwords in there since 3 decades or so)
You're probably still somehow™ relying on homed??

Re: [SOLVED]systemctl user environment

Not sure what did unlock my issue (my ~/.config/environment.d/10-envars.conf ?), but after log out/log in:

gabx@magnolia ➤➤ ~ % systemctl --user show-environment | grep HOME
2:HOME=/home/gabx
7:SYSTEMD_HOME=1
8:SYSTEMD_HOME_SUSPEND=0

Re: [SOLVED]systemctl user environment

With

Directory: /home/gabx

I'm not even sure what would be the problem itfp, homed probably should™ set a proper $HOME…
