commit bf81e792f3c0aed54edf004c1c95cc6f6d81d0ee
Author: Tom Gundersen <teg at jklm.no>
Date:   Thu Mar 27 21:47:14 2014 +0100

    udev: persistent naming - we cannot use virtio numbers as they are not stable
    
    This reverts commit 8741f2defaf26aafe5ee0fd29954cfdf84ee519c: 'Add virtio-blk support to path_id' and
    commit e3d563346c4237af23335cc6904e0662efdf62ad: 'udev: net_id - handle virtio buses'.
    
    Distros may want to take note of this, as it changes behavior.
