Resolved Create login screen message on a machine running FileVault?

[bedouin]

I know that it is possible to create a lock screen message on a machine that is running FileVault, but is it possible to create a login screen message? It seems that this might be tricky since the boot process does not really even begin until a password is entered. Any thoughts?

I found an answer here:

It asked for my iCloud password on reset, but otherwise went as expected.
