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.
JFC, as a business owner I 100% not expect my employees to be reachable after hours. Why do these idiots don’t understand the basic principle: happy employee is productive employee. Understanding life happens and work is ‘just’ work. Give and take equally, be reasonable about stuff - basic human empathy… I hold my own personal time in high regard, it would be insane not to hold other people’s personal time in high regard too.
