The way I read it, saving the RW branch back into AFS is an explicit
user-specified "save" operation (step 4 in "Environment In Action").
When the actual program runs, the user overlay is still RO and isn't
modified, and as far as I know could be another AUFS branch into just a
different RO volume in AFS. I may not be interpreting that correctly,
And yes, thanks for posting this! It was interesting to read. Just so
you know, though, DFS is the actual name of a couple of other
filesystems (DCE/DFS, and Microsoft DFS), and the DCE one was supposed
to be an AFS replacement.
