If you're making heavy use of either NFS or layered file-systems (such
as umapfs/unionfs) you should be able to note if something is wrong. If
I knew exactly what might trip kauth(9) I'd test it myself... the reason
I posted is so that people could try their existing configurations and
report back if anything breaks.

Since the changes were made -- literally -- all around the kernel, I
can't be more specific...

Of course that if you run this code on your own machine doing the same
things you did prior to kauth(9) for a week it should be a good
measurement that things work well. :)
