Yes, I think I've seen it too, and I am not sure why it happens. There is
explicit code in /etc/init.d/knoppix-autoconfig:

# edd 21 Nov 2005
if [ -d /proc/hpc ]
then
    /etc/init.d/portmap start
    sleep 1
    echo "Starting openMosix."
    sleep 1
    ( cd /usr/share/knoppix-terminalopenmosixserver/ && \
        cat templates/miniroot/etc/fstab >> /etc/fstab && cd - )
    [ ! /mfs ] && mkdir /mfs
    /etc/init.d/openmosix start
    sleep 1
    /etc/init.d/openmosixcollector start
fi

With this, openMosix started correctly on all my tests when I booted
"normally", i.e. a machine rebooted into the iso.  But after the release of
0.7.9.1, I noticed that e.g. this code would not execute when the iso was
started with VMware Player. I suspect that may be due to /proc/hpc not being
there in an emulated/virtual session. Any additional light you could shed on
this would be appreciated!

Keep in mind that we do not want this under kernel 2.6. So we do need a test,
but maybe a more robust one?  Instead of testing for /proc/hpc, maybe testing
the uname output is better?

Sure thing! Such a fix should definitely go into 0.7.9.2 as these are the
little things we are trying to get correct on incremental releases.
