[ I'm new to kernel modules. ] kldload() can be passed a kernel module filename with path and the kernel links the module as expected, stripping the path and assigning the module name to just foo.ko (instead of ../../foo.ko or /somepath/somewhere/foo.ko). kldfind(), on the otherhand, wants just the module name after the kernel has silently stripped the path. I was expecting to format a string containing the explicit filename I wanted to load (under test, before any eventual installation on /modules), call kldfind to see if the module was already loaded and if not, pass the same string to kldload(). This code results in *lots* of copies of the same module getting loaded -- until I noticed, that is. I think kldfind() should accept the string with the path and behave like kldload() does. And kldload() shouldn't allow more than one module of a particular name.
