Not guaranteed, but it works within a massively more constrained
environment and so certain fundamental issues don't apply. yum
distro-sync requires that all currently running applications are able to
deal with their files being replaced. Preupgrade doesn't. That's a
pretty obvious distinction, and it's why preupgrade is supportable in a
way that yum isn't.
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!
