afs provides copy on write. i dont know very many (zfs is the only one
that comes to mind) that implement this feature natively.
afs's namei based filesystem could provide a more familiar layout
of the files. however, i suspect the designers choose the current
structure to avoid creating single directories with huge numbers of
files. most filesystems dont handle this well.
