Well, I had encouraging but mixed results: with the
zipl-installer_0.0.32 udeb the boot setup was completed correctly.
However, the system still didn't get up because the DASD(s) holding the
root LV were not set online in the initramfs because the
sysconfig-hardware in Jessie lacks the initramfs hooks (you wrote that
in your blog back in October but I forgot that...).
Enabling the DASD in the emergency shell and activating the volume group
led to successful completion of the system boot.

That means it will be necessary to also update the sysconfig-hardware
package (e.g. to 0.0.10+nmu4)). I lack the skills to tweak my Jessie
mirror to upgrade the package there, so there's a still some residual risk.

True, there could be more than that. I'll take a stab at it and post my
results...

That is exactly the point, Debian Jessie's installer only accepts the
root device on a DASD partition. With Stretch, root can be anywhere
including LVM volumes.
