and why is this so?
because the feature is introduced ina a hurry brainedead way!

around 350 files

well F17 -> change packages to replace them one by one
with symlinks which could be targeted without stress
even after F17 GA package for package

so F17->F18 could verify this are only symlinks
and remove them or cancel the action with a message
that this has to be cleaned up

but yes, if we make always hurry decisions without thinking
what they may inroduce finally then will always mistakes
happen - hopefully the people acting so does this not
in a payed job and nobody fires them!
