There is a simple way to do it on Debian using the policy-rc.d trick https://wiki.debian.org/chroot#Configuration Is there such thing in Centos6?

What's the question here exactly? That linked section doesn't seem to have anything to do with updates (or much of anything else) and mostly seems to be a horrible trick to prevent dpkg (at least) from starting daemons in a chroot by short-circuiting the scripts that it normally runs. – Etan Reisner Mar 24 '15 at 16:02

RPM has the ability to disable %pre/%post/%preun/%postun scripts when installing using --nopre/--nopost/--nopreun/--nopostun options resp.
Most daemons are restarted in %post, so --post would prevent daemon restart.
However, most daemons are restarted if (and only if) already enabled to be started on reboot by chkconfig(1) (or systemctl). So in practice nothing whatsoever needs to be done if the chroot is being populated by a single transaction because most daemons are not yet configured to be run.
