>Description:
The config command generates a Makefile which assumes that the kernel
being configured will be named "kernel", even if the config statement
in the configuration file says otherwise.
>How-To-Repeat:
1. Create a kernel configuration file named TEST containing the line:
config frobozz root on da0
(and everything else necessary to configure a kernel).
2. Run "config" on this configuration file.
3. Observe that ../../compile/TEST/Makefile has multiple references
to the file "kernel" instead of "frobozz".
>Fix:
The following diff to /usr/src/usr.sbin/config/mkmakefile.c will
substitute the real kernel name for all occurences of %KERNEL in
the Makefile template file:
