I have approached cesman about inclusion of a question during knoppmyth installation asking whether the user wants to run folding@home. He responded favourabley, so I have written a startup script that he can include.

When you run
/etc/init.d/folding@home configure
It asks you whether you want your system to run folding@home. Cesman can put a call to the script in the post install configuration script.

If you opt to run it, it creates the directory /myth/folding@home to do the folding in. If there is no client.cfg in that directory, it asks you for a username and creates one for you that has you folding for the knoppmyth team and then starts folding. It sets up links using update-rc.d so that it will be started during boot.
Code:
FOLDING_EXECUTABLE=/usr/local/bin/FAH504-Linux.exe
FOLDING_DIR=/myth/folding@home
FOLDING_CONFIG=$FOLDING_DIR/client.cfg

case "$1" in

start)
  cd $FOLDING_DIR
  su mythtv -c $FOLDING_EXECUTABLE > /dev/null 2>&1 &
  ;;

stop)
  killall -v $FOLDING_EXECUTABLE
  ;;

configure)

  if dialog --yesno "\

    if [ ! -d $FOLDING_DIR ] ; then
      mkdir $FOLDING_DIR
    fi

    chown -R mythtv:mythtv $FOLDING_DIR

    if [ ! -e $FOLDING_CONFIG ] ; then
      dialog --clear --inputbox "\

   /tmp/folding@home.username || exit
      FOLDING_USERNAME=$(cat /tmp/folding@home.username)

      echo "[settings]" >  $FOLDING_CONFIG
      echo username=$FOLDING_USERNAME | tr ' ' _ >> $FOLDING_CONFIG
      echo team=50975 >> $FOLDING_CONFIG
    fi

    update-rc.d -f folding@home remove
    update-rc.d folding@home defaults 99
    /etc/init.d/folding@home start
  else
    update-rc.d -f folding@home remove
    /etc/init.d/folding@home stop

For those that are already folding, before upgrading to the next release of KnoppMyth when it is released (post D1), if you are folding on your myth partition somewhere, rename the directory you are folding in to /myth/folding@home before you auto-upgrade. When you opt in by answering the question during the install, your folding should simply continue where it left off when the upgrade completes (assuming there is no incompatibility between the new version of folding@home 5.04 and the version you are currently running).

Hi Greg Frost,

Just a view point from my direction, however would you consider making the setup question an offering for the "opt in" rather than the current have to "opt out" ?

Thanks
Mike

The question is already "Do you want to opt in"? I would hope that most people would. There seems to be little reason not to.

Heat. I used to run Folding on all my work machines, but apparently it was too much for my main desktop. As far as I can tell, the heat from the P4 running all the time at 100% baked the hard drive.

It certainly would be interesting to see if the membership goes up once R5Exy is released. It is amazing to think that such a relatively young team with such few members is in the top 200. It certainly would be nice to break the top 100!

I think we'll get there... it's just a matter of time.

The installation script was a great idea BTW.

Not much... Since the release, not many people have joined considering the amount of downloads we've had...

I started a few weeks ago before the new release. I'm hoping we start seeing more people with this release.

I haven't upgraded my knoppmyth boxes yet, busy with the holidays.

From what I have read it ask you to opp in. Does it also let you know what script to run later on if you decline on the install?

Gnarl it may be helpfull to update the original post with that information.
