Re: GENERIC kernel "modules" implementation info?

No, modules aren't dependent on the kernel config, so there's no
need to build them each time.  Your " install DESTDIR=/"
command is probably what built them.

hmm... how is the kernel supposed to load the modules if the code to
mount the filesystem is a module itself?  On Hubert's blog there's a
post tha lists the output from modstat as having a "SOURCE" column,
and ffs shows up with a source of "boot".  (other values are "filesys"
and "builtin")  None of my machines has a sufficiently up to date
modstat man page to explain what those values mean, but I'm guessing
that "boot" means something like "loaded by grub" (which can load
more than just the kernel)
