Yeah. Here's my startup script to run my local Swiki. You'll need to
tweak the paths, usernames, etc. but this should show how to do it.
start-stop-daemon is great!
After installing this script in /etc/init.d, you need to cause it to get
run. I use file-rc, and so I edit /etc/runlevel.conf to accomplish
this. With the default setup, you have to create symbolic links in the
/etc/rc?.d directories.
Overall, there certainly are an annoying number of steps to getting
something to start after every reboot, but it is all straightforward.
Given start-stop-daemon, you can make Squeak auto-start at boot time
much like you'd do so for any other Unix program (sendmail, apache,
squid, whatever).
