So you are on the latest version of open-iscsi.

I think Christian did a great deal of work in the last year to get the
integration much stronger. And given that you are using the latest version
(backports), this surprises a bit.

But if I remember correctly, neither of us talked about dm-crypt/LUKS when the
integration was being revived. sanboot and DM-LVM were common setups and we've
tested them.

I still have my setup in place. Perhaps I should first look into what I have,
and maybe have an additional setup covering dm-crypt. I'm still wondering why
dm-crypt will break when the other dm target is working. With a setup in place,
it may be easier to see why.
