Probably a good idea. I just had in mind that we need to adjust
the defconfigs then to still have a working defaultenv.

How about making it optional and combined with your defaultenv-Kconfig
patch we could do a

	select HUSH
	select HUSH_GETOPT

to make sure all commands needed by the defaultenv are in place.
