fix booting from btrfs on multiple devices https://btrfs.wiki.kernel.org/index.php/Using_Btrfs_with_Multiple_Devices: > btrfs device scan is used to scan all of the block devices under /dev > and probe for Btrfs volumes. This is required after loading the btrfs > module if you're running with more than one device in a filesystem. See http://bugs.alpinelinux.org/issues/6903
