The dotfiles clone used to land directly in /mnt/etc/skel, gated solely by
clone_skel_dotfiles. That meant run_tui=YES + clone_skel_dotfiles=NO cloned
nothing anywhere, so tui-install.sh (which only exists inside the repo, not
in the embedded live-ISO scripts) had nothing to run and the TUI step always
failed.
Clone the repo once into the live environment ($HOME/Dotfiles) whenever
either toggle is YES, then serve both the skel copy and — as a fallback
right before the TUI runs — a direct copy into the new user's home from
that single clone, no extra network fetch needed. arch-autoinstall.sh's
skel clone also moved out of the chroot heredoc so it can share the same
live clone.
When clone_skel_dotfiles=NO, the fallback copy in the new user's home is
transient: after tui-install.sh finishes, materialize every symlink that
shell-setup.sh/hyprlua/hyprland/niri point into ~/Dotfiles (shell rc's,
nvim/starship/alot/yazi/spotify-tui configs, config-updater scripts) into
real copies, then remove the checkout — so declining skel persistence
doesn't leave a system full of dangling symlinks.
