v0.5.5 fixed AnacondaError: 'LANG'. Auto-install harness then
hit next crash:
TypeError: expected str, bytes or os.PathLike object, not NoneType
File "/usr/lib64/python3.14/site-packages/pyanaconda/display.py", line 223
wl_socket_path = os.path.join(os.getenv("XDG_RUNTIME_DIR"), ...)
anaconda's display.setup_display() unconditionally tries to set up
Wayland socket path. tty1 has no XDG_RUNTIME_DIR set. None gets passed
to os.path.join → TypeError.
Two-part fix:
1. export XDG_RUNTIME_DIR=/run/user/0 + mkdir, so even if anaconda
probes it, the env var has a valid string value.
2. Pass --cmdline to anaconda. Fully unattended text-only mode, no
Wayland/X/TUI. Right fit for our gum-driven kickstart flow where
ks is self-contained (disk, pw, locale all pre-answered).
Combined effect: anaconda goes straight from CLI parse → kickstart
execute → reboot. No display subsystem at all.
Surfaced by test/auto-install.sh round 2.
