Hi,
As an heavy nanobsd user on headless (serial/IPMI SoL) appliances, being
able to early select the boot partition by MBR/boot0 and configuring early
message redirection (with boot.config) is very useful.
Not being able to do the same with GPT/EFI is the feature preventing me to
upgrade my nanobsd image scheme.
So if there is a way of displaying EFI boot loader messages over
serial/IPMI SoL and selecting boot partiton, I've no objection to remove
boot.config support.
