Just to let people know: in a private mail Toomas had later on provided a
fairly simple workaround that only required patching one line in setup-storage.

In 4.0~beta2+experimental60 I have now made the troublesome line guarded by a
check for preserve_*:all being in effect. If that is the case, no strict (but in
some sense stupid) layout checking will be performed (as the layout had
previously been valid anyway). Toomas, if you still have access to that
particular system, could you give the new experimental version a try? I'm a bit
too lazy to reproduce that over here :-)

Thanks a lot for debugging and all the info,
