commit 6c8d7408095782bb00b5361a7df5973f3dcda183
Author: Jonathan Brassow <jbrassow@redhat.com>

    clogd:  Fix for bug 455453: small mirror creation fails
    
    Was setting the checkpoint attribute 'attr.maxSectionSize'
    with the size of the bitmap.  However, when mirrors are
    really small (<= 30M) other sections may have a larger
    size and need to considered.
