Implicit modularization still > confuses me (unlike in linux, where you explicitly state static,module,or don't-compile). I have _nothing_ relating to smbfs in my kernel, and mount_smbfs works just using klds. The only place I've seen a problem with just using klds is on SMP machines. In those cases, I had to statically include the smbfs stuff in the kernel. Joe > > On Sat, Feb 02, 2002 at 01:29:58AM -0500, Joe Clarke wrote: > > On Sat, 2002-02-02 at 01:09, Peter C.
