[Zope] Hairy problems deinstalling zfs???

[Andy McKay]

When I remove ZFS from my Zope, all that happens is the ZFS product becomes
broken, nothing else. The rest of my site is perfectly workable.

At runtime ZFS changes this attribute so that it can do some ZFS hacking.
There is no reason this attribute should have this error. Could you tell me
what other products you are using, and the traceback?
