Description David Woodhouse 1999-01-18 12:09:46 EST
The rc.local script generates a line like "Kernel 2.2.0-pre5
on an i686", even on SMP machines which should read "Kernel
2.2.0-pre5 on a pair of i686s".

Try something like:

arch=$(uname -m)
a="a"
case "_$arch" in
        _a*) a="an";;
        _i*) a="an";;
esac



NUMPROC=$[`cat /proc/cpuinfo | grep ^processor | wc -l`]

if [ "$NUMPROC" = "2" ]; then NUMPROC="a pair of"; fi

if [ "$NUMPROC" = "1" ]
then
  TAILBIT="$(uname -r) on $a $(uname -m)"
else
  TAILBIT="$(uname -r) on $NUMPROC $(uname -m)s"
fi

# This will overwrite /etc/issue at every boot.  So, make
any changes you
# want to make to /etc/issue here or you will lose them when
you reboot.

echo "" > /etc/issue.net
echo "Red Hat Linux $R" >> /etc/issue.net
echo "Kernel $TAILBIT" >> /etc/issue.net

Thank you for the suggestion. It has been noted and will be considered
for upcoming releases.
Comment 2 David Woodhouse 1999-05-03 07:14:59 EDT
This 'bug' still exists in 6.0, and can more realistically be called a
bug now that SMP is officially supported.

Even though it's only cosmetic, it's the first sign many people will
see as to whether Linux is using more than one processor or not - and
it gives the wrong impression. I expect that this will lead to much
confusion as people wonder 'why is it only using one'.

Even if the logic I gave isn't acceptable for some reason, consider
changing the message to "Kernel `uname -r` on the `uname
-a` architecture", to remove the implication that there's only one
processor.
Comment 3 Bill Nottingham 1999-05-04 15:45:59 EDT
Will be fixed in next initscripts release (4.17-1).
It will say something along the lines of
'Kernel 2.2.6-14smp on a 4-processor i686'
