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.

Two user-visible polish passes on top of the walking-skeleton install:
- Console welcome: live ISO's getty no longer shows the bare Arch prompt.
`/etc/hostname` is now `proksi` so avahi advertises `proksi.local`;
a systemd oneshot (`furtka-issue.service`, runs after
network-online.target) regenerates `/etc/issue` via
`/usr/local/bin/furtka-update-issue` to show both
`http://proksi.local:5000` (preferred, via mDNS — avahi and nss-mdns
are already in `packages.extra`) and the raw IP as a fallback for
networks where mDNS is flaky. `agetty --reload` nudges the already-
running login prompt to redraw.
- /install/log now polls a JSON endpoint (`/install/log.json`) every
3 s instead of meta-refresh, so expanding the collapsed log
`<details>` doesn't get eaten by the refresh. Noscript fallback
keeps the meta-refresh for JS-off users. When the install finishes,
the Done state shows a Reboot-now button that POSTs to
`/install/reboot` (guarded server-side to only reboot once status
is "done", so a panicked click mid-pacstrap can't brick the box).
A confirm() reminds the user to pull the USB / eject the ISO first.
End-to-end tested on a Proxmox VM 2026-04-14: boot → wizard →
archinstall → Done state → Reboot now → VM came back up → login as
created user → `docker ps` worked.

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.
