To generalize this verb we probably want leafVolUUID to be optional.

Line 1841:             curChain = img.getChain(sdUUID, imgUUID, volUUID)
Related to a following comment below: this logic seems to belong to image.py 
(it should be relevant to this patch as you're calling it from 
reconcileVolumeChain).
Line 1842:             subChain = []
Line 1843:             for vol in curChain:
Line 1844:                 if vol.volUUID not in newChain:
Line 1845:                     subChain.insert(0, vol.volUUID)

leafVolUUID=%s" %

argsStr))
Line 1874:         dom = sdCache.produce(sdUUID=sdUUID)
So we're not enforcing this verb as an SPM verb?

All the logic doesn't belong here. It should probably go in image.py.
