Regarding confusability, I can see potential problems in the interpretation of offsets (absolute or relative?), such as for nested BSD labels (discussed in another thread). Do you see other potential causes for confusion? > 2) Support for embedding. > Embedding is a potentially dangerous operation so we have to be > cautious.

As discussed on irc, this would require in-depth changes to grub-setup, and it's worth another thread... Grégoire
