Space low on root partition, /usr/lib
I have the following problem: my root partition (/) starts to fill up completely. I checked it out and what takes up most of the space on it is the /usr folder, and inside of that the biggest one is /usr/lib (~2Gig). I've been wondering how I could solve the situation:
By using some partition editor to increase the size of the / partition -- but there are always these warnings that data loss is possible etc. that I'm not really sure how reliable this would be. Also, then I'd have to create/download and boot some rescue CD I suppose in order not to have the partitions on the hard drive mounted... lots of hassle, great risk.
I had an idea that I'd move over some folders from /usr/lib to some other partition where there was enough space and created soft links to them in /usr/lib. (I wouldn't dare move the whole /usr/lib folder because I'm not sure whether there is something in there that's actually needed to mount the partition I would move it to -- which would be pretty much of an own goal.)
The problem here is that if I only move individual folders (e.g., "Adobe"), then they will have relative references to other files like ../../../../../liblber-2.4.so.2 which are only present in the original /usr/lib, of course.
Any ideas how this could be solved relatively simply?
