Introducing /run

Unix is like math. Despite what your programming teacher may have taught you, shorter names are actually easier to grok for most things, variables and directories included. Ever wonder why algebra and physics is still taught using x, y, v, s and not unknownNumber, mySpeed, distance... Because it is easier to read, not just to type or write.

The root directories are common directories that everyone familiar with unix should know, these are not obscure directories that you see once while investigating a deep application sub directory and wonder what it is. It makes sense to make the common easier for the experienced users and not the newcomers. Newcomers will ask once and then remember, in the mean time, the rest of us can benefit from short simple directory listings and paths. This is not elitism, this is simply better usability.
