In 0409f691 (zope4: Handle log rotation following Zope documentation.,
2022-03-10) we added an option to use copytruncate in logrotate, with
a default value of "false" which is true in jinja2, so it was actually
enabled every where.

This change brings the expected behavior copytruncate option in
logrotate stack, it is not enabled by default, unless explicitly using
copytruncate = true

This can be helpful when comparing measurements or more generally when
trying multiple versions

this is a wrapper independent from where the part got installed

no reason to have an exception here.

CPU temperature promise will now come from monitor SR

When re6st is running with tunnels, the IPv6 packets can come in through
an interface and go out through another. This is expected.
