Uh.. Terry.. have you even looked to check what this new kldconfig thing is supposed to do? :) kldconfig(8) does not traverse any directories; it just modifies a list of paths. As other posters in this thread have made me believe, it doesn't even need to check for the existence of the paths. The only kind of path traversing in the KLD case is done at module-load time, by the linker_search_path() function in sys/kern/kern_linker.c, invoked by kldload() syscall defined in the same file. It is there that any kind of checks should be made (currently none, though I plan on addressing this soon, in a very-very-very simple way, if Robert Watson doesn't do his MAC thing first :). kldconfig(8) just reads a sysctl value, parses it into a list of paths, parses some user-specified options, adds or removes paths as appropriate, and sets the sysctl value back.
