The reasons for the /usr merge make a lot of sense, and I'm glad the arbitrary and confusing distinction between / and /usr are going away.
However I still don't really understand why dispatching of /usr and sending its directories into / isn't sensible. The only reason given in Fedora's FAQ is that it would mean mounting a few more network shares to get the OS over the network, but that doesn't sound like much of a hurdle to me. I'd just like /bin to contain all binaries, directly (not as a symlink). This solution has the most clarity to me. Can anyone explain slower why merging to /usr rather than to / is significantly better?
