Python 3.14 added pathlib.Path.copy() which refuses source==target with
OSError [Errno 22]. archinstall's sync_log_to_install_medium() calls
.copy() on install.log to itself at __exit__ time, because by then the
chroot mountpoint is already torn down and both source and target
resolve to the same /var/log/archinstall/install.log. The install
itself has already succeeded — the crash is in the log-sync cleanup.
Patch is a pre-start sed on the live ISO that replaces the offending
call with `None` (a no-op expression-statement keeping the same
indent level). Lives on furtka-webinstaller.service as ExecStartPre
so it runs before the first install attempt; idempotent, so service
restarts don't re-trigger anything. Never touches the installed
system — only the live ISO's site-packages tree.
Real fix is upstream in archinstall (guard the copy when source
and target resolve equal); this is a workaround until they ship it.

iso/build.sh runs mkarchiso inside a privileged archlinux container,
overlays our customizations onto Arch's stock releng profile
(systemd unit that launches Flask on 0.0.0.0:5000, the webinstaller
under /opt/furtka, extra packages for python/flask/avahi), and drops
a hybrid BIOS/UEFI ISO in iso/out/.
Verified end to end: Proxmox VM (OVMF, Secure Boot off) boots the ISO,
DHCP's onto the LAN, and serves screens 1-3 of the existing wizard at
http://<vm-ip>:5000/install/step1. This is the first point at which
Furtka is something you can run instead of something you can read about.
Two known drive-list bugs surfaced while testing (/dev/loop0 and
/dev/sr0 appear as install targets) — captured in the README roadmap.
