As you may know, frequent bugs arise when the root (/) partition is full or nearly full. Amongst them : impossible to start a graphical session, random bugs on desktop such as error with clock applet... so it is hard to know that the origin of these bugs is the full / partition.


Problem : currently the user is not warned about such risks when his root partition is full. Consequently, he has bugs but does not know he has to empty his disk to solve them.

Proposed solution :
We could make the notification pop-up window (gdu-notification-daemon?) more explicit, so that the user knows the risk he takes if he does not quickly free space. Example of explicit message :
"WARNING ! Your system may not work properly (random bugs, impossible to start a graphical session ... ) because the volume <<root file system>> only has 18Mio of free space left. ["More details" button].
Please free disk space. A minimum of xxx Mio free space on this volume is recommended.
You can free space by ... (rest is same as currently)
..."
The "More information" button could, for example, explain the technical reason (system needs to write in /tmp at start-up...).


Hope this helps make GNOME better.
