[parted-devel] freaky loop device handling

[Joel Granados]

The loop label might be used to detect device-mapper filesystems (like
those found in an LV).  From this another two questions stem out:
1. Why is it called loop? And 2. If its only for device-mapper detection
purposes, why is it working on a real device?

any insight appreciated.

Regards.
