Why CONFIG_EMBEDDED? You probably mean CONFIG_EXPERT, but then what do
you need that for?

TBH, I have no special requirement for this option to be set and now,
looking at Kconfig entry for this option, I think that I got it here
because I stated configuration with allnoconfig.

OTOH, I don't see how harmful it can be since description says:

          This option should be enabled if compiling the kernel for
          an embedded system so certain expert options are available
          for configuration

yes, it selects CONFIG_EXPERT and that had side effect that, for
example, CONFIG_NAMESPACE could be compiled out.

Have I missed something around it?

Thanks
Vladimir

Just the history behind this symbol. We removed it a while ago in
favor if CONFIG_EXPERT, assuming that it makes it clearer that it's
not just for embedded systems, or for systems with small memory.

It's  basically a zombie symbol that nobody should use directly
(independent of what the documentation says...).

Good to know! I'll drop it then.
