They are not nice, but quite a bit different, as we are trying to execute
them, which can't have bad side-effects in case they don't exist.
What nfsd does is expecting a directory to be present on which it can
do various operations. That's much worse then trying to execute or
even read from a file. Besides that all this directory handling really
belongs into userland as pointed out _three times_ now.
