Upon initialization, ADM presents two choices for file systems. Ext4 and Btrfs. Which is the correct choice?
EXT4 and Btrfs are two popular file systems used in Linux. On ADM, these two options appear during initialization. Because ADM is based on Linux, Ext4 and Btrfs are both supported. Each have their own advantages and disadvantages; EXT4 has a long history and is known for stability while Btrfs is relatively newer. Btrfs also brings different features, including, but not limited to snapshot support.
