Well, but what about after R1? I know it's too early to say, but I think this
is a matter that we had better talk about from now.
My main concern is that if BFS gets replaced by something else (I hope not),
the data stored with it might be at risk. Even with the proper tools for data
transfer, it could happen that not all the data will be safely transferred.
As I pointed out in a previous message, my worry are the extended attributes,
which in BFS are unlimited, while in other filesystems, as far as I know, are
subject to limitations (in number and size). What would happen, for example, if
I have a lot of extended attributes for a single file, and the target
filesystem to which that file is being transferred can only support a limited
number of attributes? Part of the stored metadata would then be lost. This is
my worry.
That's why I would be happier to stay with BFS, and see it being further
developed, rather than moving to ZFS or to some other filesystem.
