[PD] is /etc/rc.local the script that runs on boot?

rc.local runs as root ... to launch pd use:

sudo -u pi -i pd -nogui -noaudio -nomidi /share/master.pd &

or similar, here pi is the user, the & means pd runs in the background.

I usually keep a script at /share/initialise then call it as user pi, it makes 
it a lot easier to keep different projects ans swap between them.
