I noticed yesterday that the Application Manager complained of memory being full. that was followed by a lot of 'Operation Failed' messages.

'df' showed that the root partition was at 100%. So I quickly removed a bunch of applications and was able to bring it down 88%.

This is worrisome because I have been using this for only 2 weeks and now have only a small number of apps installed. I am afraid this will hit 100% very quickly again. Is it due to apps not optimized to install correctly in /opt? many apps it seems have files both in / and /opt. How will it possible to manage the small amount space in '/'?
