[Buildroot] making a second small failsafe file system

I have a board with 8Mb of NOR and 256Mb of NAND.

I plan to normally use NAND, divided into redundant halves, but if
neither half can boot, I would like a failsafe minimal file system on
NOR in order to re-image NAND over the network.

What are my options?  

Do I maintain a separate buildroot just for that failsafe?

Should I create a post-build script that assembles a tiny file system

Has anyone tired this?
