And wondering if we can use this technique to save the boot partition for master.

Thanks,

Any other ideas about how to deal with this problem?

Another option would be to get rid of the master rootfs entirely run
everything master-ish from a initramfs.  Dunno how feasible that is
though.

Paul and I discussed this back in SF. I think it's worth running up a BP and investigating. Would solve a lot of problems.

I've been interested in that concept as well. I'd been hoping that we'd get SD muxes and just not have to think through things like this. However, I think the SD-mux is still at least 2 months away.
