So far, the Solus installer stays on a Qwerty layout, but does perform the mkinitcpio hooks that turn the keyboard at the FDE password time into an alternative layout (e.g. Dvorak) on the second boot, which means that instead of not working on the first boot, it doesn’t on the later ones (which isn’t ideal if you use a YubiKey, or at all really).

As usual I’ve worked around this problem by setting a Qwerty layout at install time, and changing it after rebooting.

When I need to enter my password to unlock my session, the layout stays on Qwerty, which isn’t elegant… Because there’s FDE anyway, I’ll just try to remove this prompt.
