I prefer runtime configuration. Solaris has two filesystems UFS, ZFS.
ZFS offers strong error detection and a another CRC is overhead. You
need mechanism how to enable this feature on UFS and disable on ZFS. I
suggest to have it as tablespace property and for default tablespace you
can setup it in initdb phase.
