Boot the stick, pick one GRUB entry, walk away: it wipes the target disk, installs Ubuntu
26.04.1 with the NVIDIA driver and codecs, and runs setup.sh on first boot to install the
apps. build-iso.sh does the image surgery in a container, so the build machine needs nothing
but podman.
The wipe is pinned to one disk serial (the 990 PRO). The Data drive can't match it, and an
unmatched disk stops the install rather than guessing — so the stick can't eat another
machine either. The autoinstall entry is not the GRUB default, so an accidental boot lands in
the ordinary Ubuntu installer.
Verified by running the install in a VM with two virtual NVMe drives carrying the real
serials: unattended start to finish, target partitioned and installed, Data disk byte-for-byte
identical, and late-commands left /opt/main-desktop plus the enabled first-boot service in
place. Testing caught the autoinstall args landing after '---' (where they reach the installed
system instead of the installer, and do nothing), and the first-boot run adding root rather
than ckoch to the docker group, since runuser leaves $USER alone.
setup.sh gains an unattended mode for that first-boot run, waits out the dpkg lock that
Ubuntu's own boot-time upgrades hold, waits for snapd to finish seeding before removing the
Firefox snap, and skips the driver step on machines with no NVIDIA card.

Replaces the Bazzite/BlueBuild image with plain Ubuntu. apt covers the system
and dev tools, Flathub the desktop apps, and three scripts do the rest:
backup.sh archives this machine's home to server-marvin and reads it back to
verify it; setup.sh builds a fresh 26.04 install (NVIDIA 595-open, Docker with
GPU access, Steam/Lutris, 27 Flatpaks, VS Code, Claude desktop, the Data drive
and marvin mounts); restore.sh unpacks the backup without the Fedora/KDE parts
that would fight Ubuntu.
The app list comes from a scan of the running machine. The 15 Flatpaks left
behind sit commented at the bottom of flatpaks.txt, and their data still rides
along in the backup. No Node or .NET on the host by choice — LudosData and
landingPage build in Docker.
Drops the BlueBuild recipe, the cosign key and the old dev-setup script. The
Bazzite setup stays in this history.
