Yes, this basically means switching the primary (/boot/common) and secondary 
(/boot/common/something) folders. Instead of /boot/common/packages/contents you 
have /boot/common/legacy as secondary. This is a good thing for /boot/system 
since the legacy part would not exist there.

You get the same need for a legacy folder with the symlinks Ingo mentioned, btw.

I should add another disadvantage to the list, though: The set of "real" 
folders needs to be decided up front since they are effectively banned for use 
in packages. Or you could say that there is a list of folders that are ok in 
packages, and any others are not guaranteed to work.
