I don't think many people (anyone?) uses the transient exception store
for that very reason.
The future merge operation *could* allow you to at least merge any
changes into the origin before you delete the snapshot, but I'm not
sure anyone will pay attention to that exception store.
Since you are writing data to the COW anyway, you might as well write
the metadata information too (use persistent exception store).

Hello list,
I'm newcomer here, so nice to meet you all!
Is there any way to access the data of the COW device ( in transient
mode) right before discard the changes?
I tried to figure out myself, but cant find a clean way to get the
data before it gets discarded, and dont know exactly how to figure
what blocks are saved in the COW partition.
thanks.
