Replaces the gnome-terminal-launched installer.sh session with a
browser-based kiosk (opt/tuxflotte/kiosk/start-kiosk.sh launching
Epiphany with --profile). Sets German keyboard layout for the
graphical session (vconsole.keymap only covers the text console),
suppresses Epiphany's default-browser prompt, hides desktop icons,
and reduces the panel to a window list + power applet. Also disables
the SELinux troubleshooter desktop notification, and copies the full
live-updates tree (not just etc/) so opt/ payload ships too.
Several Epiphany invocation modes were tried and discarded before
landing on plain --profile=<dir> (see ADR-0004/0006 and platform-docs
history for the rejected --application-mode/--private-instance paths).

Uses dracut's official 20-apply-live-updates.sh pre-pivot hook: any
/updates/ directory tree present at the top level of the boot media
gets copied into the live root filesystem before pivoting, verbatim,
no initrd or squashfs/EROFS modification needed. build.sh assembles
this tree from scripts/, backends/, config/ (mapped under
/opt/tuxflotte) plus live-updates/etc/ (an XDG autostart entry that
opens a terminal running installer.sh as root, and a sudoers.d drop-in
granting liveuser passwordless sudo).
xorriso preserves the ownership/permissions recorded at map time, so
-chown_r/-chgrp_r 0 on /updates is enough to make sudoers accept the
drop-in as root-owned without needing local root to build the ISO.
This was tried first as a direct EROFS unpack/repack of
/LiveOS/squashfs.img (that file is actually EROFS despite the name on
current Fedora), but a fresh self-built erofs-utils (Debian's
packaged 1.5-1 can't even read this image's on-disk format) hit a
reproducible bug extracting the packed/fragmented inode into a single
corrupt file instead of a directory tree. The dracut hook sidesteps
that path entirely.
Verified end-to-end: booting either Tuxflotte entry reaches the
Cinnamon live desktop, autostarts a terminal, and installer.sh runs
through every module (network, hardware, enrollment, handshake,
device status, Bereitstellungsvorlage selection, commit point, Runtime
Blueprint resolution against the real server, full Fedora backend
lifecycle, storage detection) to a clean exit.
