The 1.5.55 release adds support for linked cells as implemented in the Unix OpenAFS client. When two cells are linked, a volume lookup in one cell that fails is retried in the linked cell. This functionality can be used to implement:
a test cell which provides substitutes for a subset of the volumes in the linked production cell
a cell renaming
a cell splitting
a cell merger
Two cells are linked in the CellServDB file:
>cell-one cell-two #Description
...
>cell-two cell-one #Description
...
aklog and Network Identity Manager will automatically obtain tokens for the linked cell when tokens for the other cell is specified.
