I suspect there was large percentage of our customers that
found it arcane rather than fun.

I think it depends on what options (if any) you run doconfig
with. Left to itself (no options) do config looks at the
currently running kernel and /vmunix to determine what is
on the system and rebuilds you configuration for you. This
is useful during the installation, but not as useful when
you want to add a driver for something that isn't on the
system yet. In such cases the option I have found most
useful is -c. It actually pays attention to the configuration
file you point it at. More recent version appear to do the
make clean first and it V4.0 it asks if you want to edit the
configuration file before it starts.
