Hi, The transmission-daemon documentation was updated[1].
[1] https://github.com/transmission/transmission/commit/b34b5193ca5de83ae85cac3c971214b17c3035f2 To customize systemd services, you should user overrides. $ sudo systemctl edit transmission-daemon.service and add the following content to the override: [Service] NoNewPrivileges=false and that override will be kept untouched by package upgrades. (you should not modify /lib/systemd/system/ files) So this can be closed I think? Thanks, Alex
