failed to install kernel

[Perry Hutchison]

There seems to be a recurrent problem, at least in 6.1, of sysinstall
not installing the kernel:

Has there been any thought of adding some basic sanity checks to
sysinstall, and at least prompting for confirmation in cases like

* About to newfs the root partition, but the selections to be
  installed do not include the kernel.

* A partition is not large enough to contain everything which the
  current selections will try to install on it.
