As stated here
it's ok to have two partitions on for Linux system files and another for home files in the same disk but they should be both the same filesystem.
Now, on one of my machine I'm running Ubuntu Gnome 16.04 LTS partitioned in this way:
- 10GB / ext4
- 482GB /home XFS
And I'm not experiencing issues at all. In fact, it seems to be running smoother than a "full" ext4 partitioning scheme. So, what's the deal? Can someone kindly shine a light on this for me? Thank you.
