There is a directory in System/Library for startup items I presume: StartupItems
I need to have a shell script that will configure ethernet interface at start up, with local network address and subnet mask. I need to do this because the network preferences for configuring the ethernet interface will NOT set it using manual settings. THIS appears to be a serious bug, or my installation is bad.
I was given the advice to use networksetup from the command line but that will not configure the ethernet interface in such a way that the configurations will be there on reboot.
The script needs to do its work with root privileges, or with sudo, but I am assuming that if it uses sudo, there will be a password dialog presented at boot time when the boot process gets to that script.
(I have had enough experience with FreeBsd and Linux to find my way around in the terminal, but not necessarily as it applies to Mac OSX)
