That's strange. I've used ULE for months on many boxes, but
much as I like it, I have to admit there are serious problems
with it. There are different reports, but it's clear you can't use
it in production environments. It might be okay to run it on your
{desk,lap}top system, though, but PC-BSD developers have
yet to comment on their reasoning.
