I see Modular and non-modular images.
Looking at this doc I'd like to confirm if it is referring to the same "modular" and if in fact modular is the recommended flavor for the redundant sup setup.

The primary benefit of "modular software" is an ability to upgrade software while switch is in service. You may upgrade the software on the switch without rebooting the switch, because each module has it's own piece of software loaded, and if it is compatible with an existing software on the controller, it will stay up while one of the controllers rebooting. As an opposite, when you upgrade "non-modular" software, after you switch control to upgraded controller, the line card software has to be loaded again and module reboots.
Good luck,

The default mode of operation for modular software is "non-modular", in which it operates EXACTLY like non-modular builds. To operate in modular mode you must use the "install" command on the image to use the 'modular' functions.
Here is on url for Cisoc IOS modular software installation. You will also here the phrase In Service Software Upgrade (ISSU) - same thing.

This is the way software installation is done on IOS XR based platforms like the CRS-1 and it works quite well.
