YunoHost “packages” are just scripts. In the case of Lemmy, Lemmy_ynh’s install script actually fetches the Lemmy Docker image and extracts the files (including pre-built binaries) from it. And then it writes the config files to use the system Psql instance instead of a containerized version.
FWIW I don’t care how YunoHost installs the apps. Whether it’s fetching and running containers, or building from source, or grabbing binaries. As long as the apps work and the reverse proxy gets wrangled it’s fine with me. Just in this case refusing to run the Docker images directly is, at least momentarily, a problem for updating the app.
What they really mean is: Polite to them, the people with the means of easily inflicting deadly violence upon others.
Gun ownership is just another expression of the deep selfishness ingrained in American culture.
