That's right, like /proc is a proc file system, /sys is a sysfs file system (similar to other pseudo file systems). They are memory based and files are generated on access, proc files mostly directly from kernel data structures, and sysfs mostly from an rb-tree data structure within the sysfs file system populated at boot. You must mount /sys as a sysfs file system in order for the rb-tree to be populated, you can't make it a btrfs file system (or any other file system for that matter).
