From reading some of the MU2 information it sounds like once it is applied to the Primaries the installation packages (including system updates) are rebuilt to include the MU2 content. It is my understanding that once this is done the MU2 updates will be included in any future deployments of the 11.2.1 system update. I am just wondering if this is correct? If not can the system update packages be rebuilt (say with zman surp) to include MU2? Basically just want to avoid another reboot if we can since we are going from 11.1 to 11.2.1 MU2.

I am going to do some testing on my own to see if I can verify at the module/version level but if anyone has any insight on this I would appreciate it.
