How to test

yunohost tools basic-space-cleanup

[olberger]

I fear this command lacks documentation, elsewhere that in ```

yunohost tools basic-space-cleanup --help

usage: yunohost tools basic-space-cleanup [-h]

Basic space cleanup (apt, journalctl, logs, ...)

Too bad.

... which place are you thinking of that it should be documented it ?

[olberger]

https://yunohost.org/fr/troubleshooting for a start ? I guess this is pretty empty so far, but never too late to start ?

You are most welcome to contribute with such a piece of documentation. 🙂

I have recently experienced an issue with a completely full disk, and the command did not help. The issue is that since it is a yunohost command, it triggers by default some logging. But it cannot log anything if the disk is full. 🙃

So, before integrating the new paragraph in the troubleshooting documentation, we need to disable logging for that command.
