I recently purchased my first Mac (MBP2010 13 inch). I have been using Linux for the past five years or so and have always had a separate partition for my /home directory. I recently used the Disk Utility to do the same to my Mac. So now I have a 100GB root partition and a 650GB /home partition (/users). I'm thinking this may not really be necessary. My questions: 1. Is this really necessary? 2. I haven't had any issues yet, but will I eventually get symlink issues or anything like that? 3. How does time machine differentiate the two different partitions when it backs up? Will I be able to (in the case of data loss) have time machine figure out the two partition scheme? I'm thinking of maybe just reverting to the original setup. Advice would be appreciated.
