It seems to be related to openssl's IPFS, you can try to disable IPFS and then run /opt/zimbra/libexec/zmsetup.pl to continue the installation.

I started installing zimbra 9 on CentOS 7. During installation, I get below error.

The system will be modified - continue? Yes

How can I solve this? I think this is related to PKCS12.
