10. Local repair

On the whole the feeling is that local repair stuff needs to be redone. At the moment the following code is present:

• LRDB (persistent)
• list of local-global fid mappings
• list of local subtree roots
• list of fsobjs, volumes, cmls involved in local repair

• lgment -- local-global map entry (persistent)
• local fid
• global fid

• rfment -- root fid map entry (persistent)
• name
• fake, global, local root fids
• parent, child fids

Numerous other structures are present, probably most can be simplified. Much of this is transient.
