            Bug ID: 257389
           Summary: MMCCAM : aliases are not correctly created for eMMC
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: kern
          Assignee: bugs_at_FreeBSD.org
          Reporter: manu_at_freebsd.org

In a MMCCAM enabled kernel we make some "mmcsd" aliases so we are backward
compatible with non-MMCCAM kernel.
This seems to fail for eMMC.

This might be related to boot partitions but needs to be checked more.
