I do not know if it is foolproof, but I would try
usermod -l gene pi
as root (or maybe with sudo; I am not sure that it would work while pi
is logged in, though).
I have used it occasionally, and the only issue is with (mostly gnome-
related) dotfiles in the login directory that contain the old login as a
string and after the change need to have that replaced by the new login.
An unfortunate number of them are in sqlite files and unless the details
are important it probably is easiest to delete them and start over.
