Hi Christoph,

As part of the VAMOS[0] research project at the University of
Erlangen we are looking at multiple integrity errors in linux'
configuration system.

CONSOLE is such a generic term that maybe someone just
expected this option exists. Or maybe it existed ages ago but I can't
find any trace of it. Anyway that code has been dead for quite some
time withoutanybody noticing so it's probably just unneeded.

As far as I can tell it comes from the old 2.0.x out-of-main-line
uClinux patches. But yes, dead and gone for quite some time.


Please keep me informed of this patch getting confirmed /
merged so we can keep track of it.

I am happy to apply to the m68knommu git tree for eventual pushing
to main-line from there.

Regards
Greg

Subject: [PATCH] There's no config CONSOLE

as there's no config CONSOLE (never has been as far as I can tell) and
noone has ever missed that piece of code, it should be safe to remove
it making the kernel a tiny bit less complex.
