Back in the day, I liked the idea of a piratebox like: https://piratebox.cc/ but the setup was too much. LibraryBox was the successor and it died as well.
Ive never tried it, but Butterbox looks interesting. If anyone knows any good backup systems let me know!
Right now, I just maintain a couple of yunohost setups because its easy and I dont have to put in a huge amount of work to get federated services up and running.
