Hi,
Can you give details about your puppetmasterd setup ? it seems that
you're using Foreman as puppet ENC.
Foreman works fine with selinux enabled : that's what we use for the
centos.org infra :-)
Which version of puppet/foreman are you using ? Note that foreman has
the foreman-selinux package that is used to automatically tune
contexts and booleans needed for this.
You can still reapply those settings with
/usr/sbin/foreman-selinux-{disable,enable,relabel}
There is no need to recompile a custom selinux policy for
foreman/puppet those days
