    Fix share-service VM restart problem

    The /etc/mtab file may have mount information such as 'nfsd'
    that if copied to /etc/fstab will cause the share server to
    hang when rebooted.

    Update /etc/fstab with exactly the newly mounted or unmounted
    shares rather than simply overwriting /etc/fstab with /etc/mtab.

    Change-Id: I67602bae1f928769d768008deca7bd0f2fef1ac2
    Close-Bug: #1639662

Hey Xiaoyang I was wondering if there is anything left to do on this defect?
