    Description

      It should be possible to allow "lfs mirror extend -N ... --no-resync" to add a new mirror to a file that is marked STALE and not resync'd before the command returns. This will allow the "lfs mirror extend" caller to specify the new mirror layout, but leave the task of copying the data into the mirror to another node (e.g. HSM agent or background scanning/resync tool).
