Howdy Yasuaki,
I know some boxes with small NVRAM (less than 64kb?) will meet many
issues if we always keep ~5kb free space.
But if we really do not keep some free space as default, many box will
become a brick. (In fact, I just fixed a bricked dell xps 8500 last
week. 5kb is not enough for dell xps...)
So maybe the better way is: we check the size of nvram and decide how
many space we retain.
