It'll work very nicely. The files are: attachments/ha/sh/hash-guid, which is a hard link to: attachments/ha/sh/hashes/hash So it's always a hard link under a child hashes/ directory. The attachments/* or attachments/*/* directories can point to any number of different mount points. Currently it's hard coded to two directory levels, allowing max. 65536 different dirs/mount points. I don't know if I should bother making this configurable.
