I don’t see real advantages for partitioning this way that outweigh the negatives - for desktop usage. For servers having separate home (and/or other dirs) partitions is great, as user fluff won’t kill the ability tor ‘more important processes’ to store stuff. If everything is kept on a single partition, the user is essentially able to DoS the system by filling up space.
Is this an EVE reference? It’s been at least 10 years since I’ve last played… ah the memories.
