Create system IPS package?
I want to create a package that will allow me to install a baseline configuration on multiple systems (had done this with SVR4 packaging on Solaris 8 & 10) for hardening and compliance. Some of these changes will touch files that are part of the core-os among other system packages. ie: /etc/system, /etc/default/login, sshd config, ...
I think using overlays are the answers, but I fear I'll only anger IPS and cause a future pkg update to a system to fail. Thus reaching out here to see if anyone has done anything like this as I can only find information for non-system type packaging.
