Hi there.
I would like some clarification with regard to the union filesystem
and mount option.
First - what is the difference in principle between mounting with the
union option (mount -o union) and the union filesystem type
(mount_union)?
Second - is there a way to have more than two filesystems stacked in a
union? So that all writes will go to the upper layer, and reads will
go down the stack until a lookup succeeds? That is - a way other than
the inelegant and probably sub-optimal way of attaching some
filesystem over an already-union filesystem to create another one?
Thank you, any help appreciated,
-- Tom
