CentOS - Mar 2020 - Weird error when installing BIND on CentOS 7

Hi,

I just installed a minimal CentOS 7 on an Internet-facing server. Installing
BIND gives me this:

Running transaction
  Installing : python-ply-3.4-11.el7.noarch
                                1/2
  Installing : 32:bind-9.11.4-9.P2.el7.x86_64
                                2/2

ValueError: SELinux policy is not managed or store cannot be accessed.
  Verifying  : python-ply-3.4-11.el7.noarch
                                1/2
  Verifying  : 32:bind-9.11.4-9.P2.el7.x86_64

Should I be worried ?

Cheers,

Niki
