Hi @jdrch, welcome to the forum!
Thanks for your input & example about service installs. A feature like you’ve described has been discussed (see below), but so far development focus has been on performance and reliability improvements over installation (and even UI) experience.
I expect we’ll get to it at some point, but if you’d like to see it sooner than later and you, or somebody you know, has experience working with installers (or wants to gain some without the normal corporate time pressure) feel free to take a look at the code over at GitHub - duplicati/duplicati: Store securely encrypted backups in the cloud! and add the feature you think is missing.
