NixOS systemd service; recommended?

[ndom91]

Hey folks, thanks for this great notification center!

I've been launching swaync through Hyprland's exec-once on startup. But I recenlty noticed that a user systemd service is shipped with the swaynotificationcenter nixpkg.

Do you recommend using that service file on nixos? If so, how would you enable it declaratively?

I'm relatively new to nixos, but setting systemd.services.swaync.enable = true; in configuration.nix doesn't seem to work, I assume it's got to be under home.nix or an import thereof to target the user systemd service, isntead of a (non-existent) system wide one?

EDIT: Nevermind, it does seem to work like so:

systemd.user.units.swaync.enable = true;

Ah okay, nevermind. After a few reboots (it seemed to work the first time 🤔) It's now errorign with cannot open display :0

I assume I have to add WantedBy or After for hyprland.service.. will report back

EDIT: Hmm it already ships with After=graphical-session.target 🤔

EDIT 2: I'm on systemd 254, so I'm assuming the CONDITION_ENVIRONMENT should be working too 🤔 🤔

will do some more digging..

I'm sadly not a Nix user, so I won't really be of much help. I launch swaync through sways exec command, the same as Hyprlands exec-once command

Hmm so after some more reboots (nothing changed) it seems to work most (all of?) the time. Maybe there was just some temporary race condition with something else 🤷

Oh well, i'll close this for now then!
