I want to be able to format my system without formatting my home, I know I can keep them seperate partitions but I would prefer if I can have dynamic sizes of each, can I achieve that by creating a sub volume for each? Would I be able to distrohop without removing my home while keeping the sizes dynamic? I never sat up a BTRFS before so I’m clueless
You are replacing partitions with subvolumes, as such you have to make these operations on the btrfs filesystem (so as others have already written, deleting the subvolume instead of re-formatting the partition).
