Comment # 11 on bug 1012504 from Stanislav Brabec

Tony Mechelynck: There are two bugs.

One in util-linux libmount that appears if two loop devices are initialized
with the same file, and -oloop=/dev/loop? is used.

Second bug is in kernel, and appears if two loop devices are initialized with
the same file with btrfs image, and different subvolumes are mounted per each
one.

YaST experiences the first bug.
