The control socket is now opened to the tsunagi group (unit), the Arch package enables and starts the service on install, adds the installing user to the group, restarts a running agent on upgrade, and depends on the libraries the tray loads at run time. The tray looks for the agent's socket again on every poll instead of once at start, and a missing indicator library is reported instead of panicking. Repository URLs unified.

Running tsunagi on Arch Linux
Install the package built for your architecture:
sudo pacman -U tsunagi-*-x86_64.pkg.tar.zst
It drops a static, dependency-free binary at /usr/bin/tsunagi, a systemd
service, and a polkit rule, and creates a dedicated system user tsunagi the
service runs as.
Start it:
sudo systemctl enable --now tsunagi
Control it with sudo (the agent's control socket is private to the service
user; sudo reaches it with no extra flags, because the CLI finds the running
service's socket at /run/tsunagi/agent.sock):
sudo tsunagi status
sudo tsunagi join <network-name> <tsn1…secret>
How it runs
The service runs as the unprivileged tsunagi user with just two capabilities
(CAP_NET_ADMIN, CAP_NET_BIND_SERVICE) granted by systemd — no root. systemd
creates and owns its directories:
| what | path |
|---|---|
| state | /var/lib/tsunagi |
| cache | /var/cache/tsunagi |
| control socket | /run/tsunagi/agent.sock |
Installing the package enables and starts the service, and adds the user who ran
pacman to the tsunagi group (log out and in again for it to apply). The
control socket is open to that group, so members can run tsunagi status, the
CLI and the tray GUI without sudo; anyone else adds themselves with sudo usermod -aG tsunagi "$USER". The group also lets its members configure
systemd-resolved for the overlay zones through the polkit rule.
The GUI package depends on gtk3, libayatana-appindicator (the tray icon),
xdotool (its libxdo), and the usual windowing libraries.
Removal
sudo pacman -R tsunagi
stops and disables the service. The tsunagi user and /var/lib/tsunagi are
left in place; remove them by hand if you want them gone.
