As a proposal for 12.2, I would like to implement the move of all binaries to /usr/ like is being done at the moment in Fedora.
Here's the details as to why this is a good thing to do, and what is involved in it: https://fedoraproject.org/wiki/Features/UsrMove
The first packages implementing this have already started to land in Fedora's version of Factory.
Before you get worried, there will be symlinks back to /bin and /sbin for those scripts expecting things to be in those locations.
We can use the Fedora patches for almost all of this, they are all published at: http://harald.fedorapeople.org/downloads/usrmove/ and a number of upstream projects are already moving their releases over to this as well, which will make things easier.
If there are no major objections, I'll start working on Base:system in December.
p.s. Please, before you respond, read the link above and all of the discussion about it and don't repeat the same questions that the link already answers.
