firstboot scripts

I have been given a directive to enable filevault on our mac's. I'm reading that there isn't an automated way to do this, but if I deploy the FileVaultMaster.cer and FileVaultMaster.keychain I can then use the Casper's Enable FV script to actually bring up the ability to enable it. So my question is... how do I copy these 2 files via my firstboot.pkg file? Or would it be better to have it as a separate package since it will be going to laptops only and not desktops? As a 2nd question... Part of my current firstboot is to enable ARD/SSH. The ARD is enabled and working perfectly. SSH on the other hand is 'enabled' but the "only these users:" field is blank. How can I enable my local admin account in there? Currently that portion of the script looks like this... # ARD Configuration # Enable ARD for macadmin $kickstart -configure -allowAccessFor -specifiedUsers $kickstart -activate -configure -access -on -users "macadmin" -privs -all -clientopts -setvnclegacy -vnclegacy yes -setvncpw -vncpw desktop -restart -agent
