The GRUB config searched for the volume by the original Fedora label
(Fedora-Cinn-Live-44), which no longer matches once the ISO is built
with its own Tuxflotte volume ID.

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.
Replaces the Fedora DVD/netinst base with a live-ISO boot chain
(root=live:CDLABEL=Fedora-Cinn-Live-44 rd.live.image instead of
inst.stage2=/inst.ks=), implementing ADR-0003. The GRUB menu now
offers two entries booting the same live image with a
tuxflotte.mode=auto/interactive kernel cmdline flag instead of a
boot-time kickstart URL - installer.sh will read this flag once it
runs inside the live session.
scripts/build.sh and scripts/extract.sh now extract the source ISO via
`xorriso -osirrox` instead of a loop mount, removing the sudo
dependency for local builds.
Verified end-to-end in QEMU/KVM: GRUB menu renders both entries,
kernel/initrd load correctly, boot proceeds to the live session.
