Thanks for this kind of reports: it will help us to improve our zope
infrastructure!

The first restart happens because zope-zshell is removed, I suppose. Did
you add zope-zshell to your plone-site instance? Anyway, it is not really
important as the next package which has been removed is zope2.8, and its
prerm stopped again plone-site and this is the right thing to do.

Removing zope2.8 should not touch your instances, and for this reason
dzhandle won't remove your products if they were installed in addon-mode
manual (as the log shows).

""
dzhandle prerm-product: denied removal of product `CMFSetup' from
instance `plone-site' (2.8) in addon-mode `manual'
"""

I do not think that this log shows any bug: everything is a normal
behaviour and intended. Your installation was quite complex, and your
plone-site instance was in addon-mode "manual" (which is the default) and
this means that the products won't be removed automatically.

This does not mean that everything is perfect: indeed, there is still a lot
of work to clean out the warning messages which could be confusing for
complex removals/upgrades.

Cheers,
