Is there a way to set up Mavericks specifically, but all OS X installs in general, so that NO data is written to the startup drive except what is absolutely necessary to start the system and keep it updated? Ideally I would like to have separate partitions for System, Users, Applications, and Fonts. Possibly Extra, Library and all the other hidden folders usually associated with the Boot drive as well. Essentially making a ROM out of the boot partition. I'm having to do an OS X reinstall AGAIN because my system drive was somehow corrupted. I've had to deal with on REAL Mac's as well as Hackintoshes with OS versions from 10.6 to 10.9. I know it's not a drive failure because I'm still using some of the same drives this has happened on, in other machines, and they have been reliable. I'm tired of having to reinstall EVERYTHING because OS X developed a problem Disk Utility tells me it can't recover from. Luckily most of my work is on a separate partition that was unaffected, and I know OS X has some nice back up tools that MAY help... For the first time I'm actually running a Time Capsule on my main system. But why recover all that data, when the problem is one little corruption? Any one got an idea if/how to get this done.
