In doing an FAI build of stretch we are seeing several messages of the form

Running in chroot, ignoring request.
invoke-rc.d: policy-rc.d denied execution of restart.


For example:
########################
...

Setting up rsync (3.1.2-1) ...
Running in chroot, ignoring request.
invoke-rc.d: policy-rc.d denied execution of restart.
Created symlink /etc/systemd/system/multi-user.target.wants/rsync.service → /lib/systemd/system/rsync.service.
Setting up tmpreaper (1.6.13+nmu1+b2) ...

########################


What does this error message mean? Can it be safely ignored?
