Hi, Grub list,

I found there's no "dd" command for grub.  Is there a reason?

In general the GRUB does not support disk writes except grubenv. Though
I think we could consider addition of dd command. However, as it was
pointed out in the other email it should be disabled at least on
platforms where lockdow/UEFI Secure Boot is enforced.

I see, thanks to both for the prompt response. That makes sense, I'll think about it.

(Btw I think I missed the email from Endres for some reason, but I can see that in the archive)
