Again, not all of us are willing to migrate away from a separate /usr
partition, least of all when that is being "imposed" by some people
trying to "shove" their pet projects to others and when we don't agree
with or acknowledge the arguments.

The symlinks will have to be part of baselayout as files get into stages
through packages and not through catalyst.
