The katello-installer already wipes this file1 but if Apache attempts to start before it's wiped then it will fail to start due to a missing certificate:
httpd27117: AH00526: Syntax error on line 21 of /etc/httpd/conf.d/pulp.conf: httpd27117: SSLCACertificateFile: file '/etc/pki/pulp/ca.crt' does not exist or is empty systemd1: httpd.service: main process exited, code=exited, status=1/FAILURE

Ensure /etc/httpd/conf.d/pulp.conf doesn't interfere
