Ah. Ugh, that sucks; I can totally see that happening. Now I'm
wondering if we should just be hardcoding boot devices as always
read-only and just refusing to write to them.
What do others think? Is there an acceptable tradeoff somewhere?
It's not clear to me that Kconfig entries are sufficient to obtain
consent to present r/w mounts of the boot partitions; the user
writing the "dd" line usually isn't the person who made the Kconfig
selection, and the person who made the Kconfig selection is often a
distro maintainer who just turns on new Kconfig symbols without
reading closely.

I'm not worried about this one, as long as they have the postfixes.
Thanks,
- Chris.
