Hi,
I like the installer very much and studied it's very interesting code but there's a small annoying issue (for the average user wanting to try Void).
When rebooting after the install is done lightdm still has the 'en_US' keyboard layout and users from non english spoken countries (as for me - french azerty kb layout) can't log in (user login and/or password).
Everything is allright for Xfce but not for lightdm. So I built an ISO with void-mklive for my language and am still looking for a solution for all languages. If I can help or give more precisions then I'll do. Thanks.
