Upon installing Leap 15 I get to the partitioning stage, where there’s a recommended partitioning scheme. Since my disk is somewhat smaller ssd, I decided to create my own scheme, with a 30 GB partition. What makes me think is that on the suggested partitioning, it says something that also 10 subvolumes are created for the / btrfs partition.
Now, I expect that to be the correct course of action for a btrfs root partition to work properly, so my question is: If I instead create a partition, mark it as btrfs and /, will the YaST installer create all the needed subvolumes automatically, the same way it’s done on a suggested partition scheme?
If you use the install defaults it should be 40 gig Sub volumes are created for root automatically as far as I know. . But in any case the the final screen before it does the partitioning will show exactly what is planed and you can modify there if needed. Not in BTRFS world sub volumes are just separate Btrees and take no additional space, Just a way to organize and optimize the file structure. .
