Hi,
I want to comment on what I'm sure has been fixed since the 1.4.8 times.
Also I apparently don't understand some of the points you make.
2) mandatory locking semantics cannot be implemented
What are these? Access to object storage does not bypass the fileserver
(except for actual data transfer). Regular AFS semantics apply, no?
Mandatory locking means that you cannot read or write while someone else
holds a conflicting lock, or more restrictively, that you cannot read or
write without holding the corresponding lock. AFS does not currently
provide this functionality, but many filesystems do, and it's a feature
that we might wish to add. I think Tom's point is that the proposed design
would make it difficult to implement mandatory locking, because the
fileserver (which manages locks) no longer mediates all read/write
operations.
