WAFL-style filesystems like contiguous space,  so if small files are 
scattered in otherwise free space, the repacker should free them.

There is no need to repack all metadata; only that which helps in 
creating free space.

For example: if you untar a source tree you'd get mixed metadata and 
small file data packed together, but there's no need to repack that data.
