I just installed 4.1 and intended to configure it with BTFS with my laptop/SSD but kept going round in circles.
When you accept the default partitioning you get LVM, but if I selected custom option and BTRFS it only gave an error saying it could not validate the disk configuration, and nowhere does it say why. I’m guessing that I needed to also set up the partitioning on my own but there is nothing that even gives a hint what sizes for what partition or even how many partitions I needed. I was just stuck in a loop until I gave up and went with the LVM default. I’ll have to redo it obviously but realized I needed to do some research, but before trying again I thought I would ask a question: Why do we not have an automatic option where you can just select between LVM and BTRFS as an option? Either that or the custom section should give a hint on what it needs to be successful.
