Ah ok, thanks for the clarification. In the end I also use Sunshine for game streaming, but for pure remote desktop access RustDesk is far nicer, since I can also quickly move files back and forth. RDP is even nicer in that regard, where I can remote-mount local devices.

Where does rustdesk not have a good reputation? I see it being recommended regularly and also use it myself heavily. Never had issues or heard about issues (that I would attribute to reputation).

True. The default rocksdb is completely unusable on HDDs. For me it runs pretty good with PostgreSQL. Dovecot was certainly easier to handle with its file based storage and was super fast. But Postfix was a pain and I can’t count how often it bit me over the years (and since it’s SMTP, that means something broke in receiving, delivery or was suddenly a spam vector, which all sucks quite hard).
