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
}
