    Because my solution works fine with userspace partitioning code (I tested
    with partx from util-linux) and has the big advantage that partitions
    actually appear at the right place in /sys/block/loopN/loopNpM. Most
    other solutions for many partitions per device failed to make the
    relationship between parent device and partition visible in sysfs.
    I haven't checked yet how EVMS handles this. Could you post
    find /sys/block/$SOME_EVMS_DISK/ -type d
    for a normal disk which is completely managed by EVMS so I can verify
    whether that would be satisfactory. Thanks.
