[CentOS] serving a kickstart file over https with self-signed certificate

I am currently using https for the --url and --repo options in a kickstart file. The yum repo files are also set to do the same. Both of them have a setting (noverifyssl and sslverify=no, respectively) and this works as expected to pass --insecure to curl. However, I cannot figure out how to also serve the kickstart file itself. ks=user:pass at url works as a url, but I get the "Problem with the SSL CA cert" error. Is there a kernel cmdline option? I have tried different variations of noverifyssl and rd_noverifyssl but haven't lucked upon the right one and I'm not finding the answer in google. This is centos6, btw.

Thanks!
