Both, but I fixed it and nothing changed.

OK, I've done that.  Still no change. {{{sigh}}}

Here's the current invocation:

start_precmd="pads_agent_ck4fifo()"

pads_agent_ck4fifo()
{
        . ${pads_agent_conf}
        if [ ! -p ${PADS_FIFO} ]; then
                `/usr/bin/mkfifo ${PADS_FIFO}`
        fi
        echo "Checking for ${PADS_FIFO}...."
        if [ -p ${PADS_FIFO} ]; then
                echo "${PADS_FIFO} exists."
                return 0
        else
                echo "I tried to create ${PADS_FIFO} and failed."
                echo "You will need to create it manually before starting 
${name}."
                return 1
        fi
}
