Probably.  I certainly find it makes an immense difference.

/usr/src/sys.  Normally /sys is a symlink to it.

If you want to rebuild a GENERIC sun3 kernel, for example, it'd be
something like this:

# cd /sys/arch/sun3/conf
# config GENERIC
# cd ../compile/GENERIC
# make depend && make

At this point, assuming everything worked, you'll find it's built a
"netbsd", which is your new kernel.
