Currently following [this guide](https://yunohost.org/#/packaging_apps_fr) to package DotClear2 blog for YunoHost, along with [the example](https://github.com/YunoHost/example_ynh).
Default YunoHost installation got a small bug that prevent `yunohost backup create`, here's the fix: `sed -i -e "302s/logging/logger/" /usr/lib/moulinette/yunohost/backup.py`
Yet it doesn't seems to save apps, at least in my test environment. To be investigated.
