Julian: if you looked more closely you would see that the 
negative numbers appear not in the available category but
in the 'USED'.  This has nothing to do with root reserve.

It may have something to do with background fsck though but
it is rather inconsistent.

989 - (-132)  ==  1G
15G - (-1.0G) != 14G
