Patch for Linux FAHClient Script

[Gorgon]

As most users running Linux have discovered the init.d startup script for Folding@Home is broken and while it starts the service it does not properly stop and reload it.

 

I found a fix for the script at foldingforum.org.

 

Stop Running Client:

killall FAHClient

Edit it adding at about line 121

echo $pid > $PID

between:

     fi

     pid=$!
+    echo $pid > $PID
     if wait_for_log_change "$LOG_STATUS" $pid; then
         echo "OK"
     else

Reload the system daemon:

systemctl daemon-reload

Now starting, stopping and reloading should work.

service FAHClient start
service FAHClient stop
service FAHClient reload

At least since Client 7.6.13 in 2020 and likely all the way back to the initial 7.6 when COVID was released as a Cause Preference

In general while FAHClient is running you  can't change the config as when FAHClient stops it overwrites the config. So to edit the config you usually need to stop the client, edit the config, and re-start.

killall fahclient

can be used to brutally stop the client then

service FAHClient start

used to restart it but editing the init script to add the Process ID (PID) is much more graceful.
