I have seen this in other distros as well but what is the bottom line?
Does this fix anything and what does it solve?
Is it really good or just change for change sake?
IMHO
It doesn't really do anything for me one way or another. I can keep it
split up or merged all together as I usually have /usr on the root
partition.
I heard though the grape vine that developers are moving out of /bin
/sbin /lib to /usr any way.
