On recent Fedora/RHEL releases, egrep raises a deprecation warning.
That warning fails selinux.fcontext_policy_present invocations.
This is especially problematic for the SELinux module for paas-docker role.
Don't record SELinux context created several times issues with nginx logs.
Patch is not needed on FreeBSD servers as on that userland, egrep works fine.
