Oddly, the script runs again if you KILL the linbpq process, and it fails again, even though it is long after the boot.
Dunno. I suppose what I should do is base the URL on yet another instance of the hostname or something else. The hostname is already specified in /etc/hosts and /etc/hostname

It doesn’t seem to succeed in doing the WGET from the web page if this is run from /etc/inittab. But when I test the script it works fine. HELP?
