Can you customize the dock with AutoCasperNBI?

Yes. You have to modify the the dock.plist with what you want.

It's in ~/library/prefrences/com.apple.dock.plist

What I did was modify it on my computer to what I wanted, and then copied that file to the NBI.

Just remember, you're booting into root, so the Dock .plist needs to go into:

/private/var/root/Library/Preferences/com.apple.dock.plist

I add a package to AutoCasperNBI that installs a small AppleScript app named "Start.app" so that provisioners can nuke FileVault-encrypted volumes easily via an icon in the Dock. The package installs the app in Applications and installs the Dock .plist in the above directory.

Hi @ahebert76 & @roiegat , I'd recommend creating a pkg to replace the dock.plist as you want.

@bmarks has the path for the plist, & I've information on the Additional PKGs feature here.
