TUAW Tip: Moving your home folder to another disk (or moving it back)
In ye olde times, with "Mack OSe 9," many users chose to keep their personal files, work, and documents on a different physical disk from their startup disk. It was a safety measure: If one disk goes down, at least the other won't. There was no structural reason to keep files in a particular disk location, other than keeping them out of the System Folder. I visited a client yesterday whose drive scheme was set up exactly like this, and he wanted to be (finally) upgraded to Leopard. I wasn't sure how Leopard would handle the fact that his Users folder had been moved to a different drive, so (knowing I had backups of his entire system) I cautiously proceeded with the installation. After the installer finished, Leopard had created a fresh, blank Users folder on the startup disk with a home folder bearing the same username. This wasn't exactly the answer I was looking for. I had to link, somehow, the new Users/hisname folder with his existing user folder on the other volume. Turns out, Leopard handles this much better than previous versions of Mac OS X. Read on to find out how.
