    Description

      For the purpose of having file versions (per-file snapshots) it is useful to have a NOSYNC flag for a component/mirror so that lfs mirror resync does not resync this mirror with the current file data.

      It would also be useful if the component stored a timestamp (64-bit seconds) that indicates when the version/snapshot was done.

            This ticket basically needs a few simple changes:

            • flag definition
            • ability to set/clear/print flag in lfs
            • check for this flag in lfs mirror resync to skip resync on this mirror (unless explicitly requested?)
