I'm running Lion on a 40GB SSD and I'm running out of disk space. What can I safely discard from the Lion installation to gain 5+ GB of free space? All my apps refer to a scratch disk for cache & temp functions. All created files are on another disk, all the obvious stuff. Thanks! Once in the past I cloned away this SSD disk and then cloned it back and it tidied up nicely, as if I had defragmented a regular HDD. But SSD's are different that way, aren't they?
