2. What is target disk mode and how is it engaged?
cp - mv - rm
Hold down T on boot - allows the mac to be turned into a very large - and expensive - external hard drive or disc drive.
It will allow any user to search any attached non-system volume if ownership is ignored.
Users don't traditionally need access to them - and if they do - they can use Terminal.
3. 6 Reasons to use the CLI
Users' public folders
Your Mac provides network routing NAT - DHCP - and DNS forwarding services for any device connected. When sharing AirPort - you can specify and SSID - channel - and WEP settings.
It starts with a full copy of the system and then it records any changes made to the system and only copies those changes. It creates a simulation of the entire system using hard links for files that didn't change.
More options than GUI - bypass finder restrictions - root access - remote ssh is invisible to users - automation easy with scripting - easy combining with ARD
4. How does resetting the master filevault password affect existing filevault user accounts?
Any Mac OS X Extended volume including volumes from disk images stored on an AFP share on OS X Server.
The user's loginwindow process does the following: Request that all user applications quit - quits any user backgroun processes - runs any logout scripts - records the logout to the man system.log - resets device permissions and preferences to defaul
If a known master password is reset - existing accounts are not negatively affected. If the master is reset because it was lost - however - preexisting accounts cannot be reset by the new password until the old FileVault passwords are reset.
It starts with a full copy of the system and then it records any changes made to the system and only copies those changes. It creates a simulation of the entire system using hard links for files that didn't change.
5. Four prep steps before installing
