Hi Ken,

Can you please post the run script that you are using for source.squeak.org?
Here is the /home/ssdotcom/run script that I came up with for squeaksource.com
running on box3. This script execs the /usr/local/bin/squeak script which in
turn execs the squeakvm executable. I confirmed that the pid of the squeakvm
is the same as the pid of the run script when it is started, and also that
the squeakvm is being run under the ssdotcom user ID. I am a newbie at supervise
but this seems to be working fine as nearly as I can tell.

--- /home/ssdotcom/run ---
#!/bin/sh
# Thu Nov 14 18:23:37 CET 2013
# run script for /usr/bin/supervise

exec 2>&1

USER=ssdotcom
SSHOME=/home/ssdotcom/SqueakSource
IMAGE=squeaksource.3.image

VM=/usr/local/bin/squeak
VMARGS='-vm-display-null'

echo starting $0 in pid $$

echo cd $SSHOME
cd $SSHOME

echo exec setuidgid ${USER} ${VM} ${VMARGS} ${SSHOME}/${IMAGE}
exec setuidgid ${USER} ${VM} ${VMARGS} ${SSHOME}/${IMAGE}

--- end of /home/ssdotcom/run ---

I also set up logging with a /home/ssdotcom/log/run script as follows. This
also seems to be working as expected.

--- /home/ssdotcom/log/run ---
#!/bin/sh
USER=ssdotcom
exec setuidgid ${USER} multilog t ./main

--- end of /home/ssdotcom/log/run ---
