This guide to Grub2 password protection references the fix in post #11.

However, in their example, instead of placing "export superusers" immediately after "set superusers", they place it after the "password/password_pbkdf2" line.

set superusers="John"
password John foo
export superusers

I'm using the latter on Ubuntu 12.04.4 LTS x86_64 just because it's from a more official source, but I'm thinking it might be better from a security perspective to follow post #11 and export superusers immediately after its been defined.

Can anyone provide any insight into what would be best practice here?
