Before enabling dconf in Home Manager, dconf must be enabled in system config. Otherwise it will fail like this: ``` $ home-manager switch Starting Home Manager activation Activating checkFilesChanged Activating checkLinkTargets Activating writeBoundary Activating installPackages replacing old 'home-manager-path' installing 'home-manager-path' Activating dconfSettings error: GDBus.Error:org.freedesktop.systemd1.NoSuchUnit: Unit dconf.service not found. ```
