# sys-apps/flatpak is not optional despite looking like a desktop nicety:
# live-iso/common/src/customize-live.sh pre-installs the TunaOS installer as
# a flatpak, and without it every guppy live-overlay build fails with
#   ERROR: flatpak not installed; cannot pre-install org.tunaos.Installer<DE>
# (runs 30159027680, 30196443189). Gentoo was the last Containerfile without
# it — every other base already installs flatpak. Same class as #809, which
# added it to the openSUSE base.
#
# app-admin/sudo for the same reason, one class over. The stage3 tarball has no
# sudo — the rpm and apt bases either ship it or install it explicitly, and
# Gentoo was the last one without. customize-live.sh writes a NOPASSWD sudoers
# drop-in for liveuser whenever ENABLE_SSHD=1, which authorises nothing without
# the binary; its assertion catches that at ISO-build time rather than letting
# every `sudo` in the E2E guest die with "command not found":
#
#   ERROR: ENABLE_SSHD=1 grants liveuser NOPASSWD sudo, but this image has no sudo.
#
# guppy:xfce, LUKS run 31082460289 — after a complete, correct image build.
#
# app-containers/podman, third of the same kind, and the one that skopeo looks
# like it covers but does not. guppy probes BACKEND=composefs-native, and the
# composefs install path cannot take fisherman's bootcDirect shortcut — bootc
# has to run in a container, which means podman in the live guest (see the
# SWAP_DISK comment in scripts/iso-e2e.sh, written from a sailfin OOM of that
# very process). skopeo is here for bootc's containers-image-proxy and answers a
# different question, so the gap read as "image absent" rather than "no podman":
# the offline store held ghcr.io/tuna-os/guppy:gnome and every probe of it was
# `sudo: podman: command not found`, so the cell fell through to the SSH image
# transfer that scripts/iso-e2e.sh documents as impossible and died on
#
#   scp: write remote "/home/liveuser/luks-image-guppy-gnome.tar": Failure
#
# 2h30m into the job. guppy:gnome, LUKS run 31134373523. Every other base has
# podman — the rpm and apt ones from build_scripts/10-base-packages.sh,
# Containerfile.arch and .debian by name — and Gentoo runs none of those, which
# is why guppy was the only variant without it.
#
# sys-fs/cryptsetup and sys-fs/lvm2, fourth of the same kind, found the same
# way: with podman in place the guppy cells got past the store probe for the
# first time and died one line into the install instead —
#
#   fisherman: fatal: missing required host tool: "systemd-cryptenroll" not
#   found in PATH — install the "systemd" package on the host
#
# guppy:gnome, LUKS run 31144015274, 3h20m in. "Install systemd" is the right
# advice on every OTHER base, where the systemd package unconditionally ships
# the binary. Gentoo only builds systemd-cryptenroll when systemd has
# USE=cryptsetup, which neither the desktop/systemd profile nor the make.conf
# USE line enables — hence the `cryptsetup tpm` grant mid-layer below (tpm so
# the enroll tool can at least attempt the TPM2 path the recipe asks for; it
# falls back to passphrase everywhere today). The grant happens here and not
# in the package.use layer above because systemd[cryptsetup] build-depends on
# the cryptsetup this very list installs — flag first meant a circular-
# dependency abort at @world (run 31158591954, see the package.use comment).
# cryptsetup and lvm2 are named here explicitly because fisherman's LUKS path
# needs the cryptsetup and dmsetup binaries themselves right after the enroll
# tool — the bootc-install refactor comments further down have said "Gentoo
# emerges neither" for a while; this is the run that made it cost a cell.
# tpm2-tss is named so the tpm dep is already installed (as a binpkg) when the

# No live-boot dracut modules needed: tacklebox injects its embedded
# tbox-live/tbox-root modules at ISO build time (tuna-os/tacklebox#90).
#
# It injects them by re-running THIS image's dracut with flags of its own, so an
# omit that only exists on our own dracut command lines below is not an omit at
# ISO time. tacklebox decides what to drop by probing for the module DIRECTORY
# (/usr/lib/dracut/modules.d/[0-9][0-9]<mod>), and sys-kernel/dracut ships the
# whole upstream modules.d tree whether or not the userspace behind a module was
# ever emerged — so the probe finds tpm2-tss "present", omits nothing, and
# dracut then rejects it because `require_binaries tpm2` cannot be met. guppy
# has no app-crypt/tpm2-tools and no pcscd. guppy:gnome, LUKS run 31111959946,

#
#   dracut[E]: Module 'tpm2-tss' cannot be installed.
#   Error: prepare initramfs for guppy-gnome ... (does the image ship dracut?)
#
# Flavor-dependent, which is what let it hide: guppy:xfce came through the same
# rebuild ("rebuilt, added: tbox-live tbox-root", nothing omitted — run

# dracut: `desktop-build` is FROM builder, not FROM system, so a drop-in written
# in `system` would reach base-no-de and no desktop image. TPM2 auto-unlock is

#
# It was NOT on the shared script, and the comment here said why: it names the
# crypt and dm dracut modules, "which require cryptsetup and dmsetup binaries;
# Gentoo emerges neither", so requesting them would be fatal, and packaging
# sys-fs/cryptsetup and sys-fs/lvm2 was the stated prerequisite. That is no

#   dracut modules 51bootc, 70crypt, 70dm   all installed

# so every module the shared config asks for is satisfiable on this base today.
#
# What the gap cost: with no drop-in, dracut never added 51bootc, and `lsinitrd`
# on that same image's initramfs matched ZERO ostree/bootc files. Nothing then
# prepared the deployment at boot, so /sysroot stayed the PHYSICAL root and
# switch-root refused it --
#
#   Failed to switch root: Specified switch root path '/sysroot' does not seem

#
# "variant 'xfce'" is the same gap seen twice: install-desktop.sh passes
# `${IMAGE_NAME:-${_TD_DESKTOP}}`, so an unset IMAGE_NAME silently becomes the
# desktop name and the codename lookup is asked for a variant that does not
# exist. guppy:xfce only reached this once the libdbusmenu USE pin let the
# emerge finish.
#
# SHA_HEAD_SHORT is deliberately NOT here: it changes every commit, and an ENV
# above the emerge would invalidate the desktop package build on every push.
# 90-image-info.sh defaults it to "testing", and the `desktop` stage below
# re-runs the script with the real value — osr_set rewrites in place, so the
# second pass corrects BUILD_ID and IMAGE_VERSION rather than duplicating them.

# On build_scripts/bootc/dracut-config.sh, like every other bootc variant, and
# AFTER ostree-layout.sh above — that script writes prepare-root.conf, which is
# where dracut-config.sh reads whether this image is composefs and therefore
# whether the initramfs needs the erofs driver. Reversed, every step still
# exits 0 and the initramfs silently cannot mount its own root. Same ordering
# note as Containerfile.debian and Containerfile.arch carry.
#
# It was NOT on the shared script, and the comment here said why: it names the
# crypt and dm dracut modules, "which require cryptsetup and dmsetup binaries;
# Gentoo emerges neither", so requesting them would be fatal, and packaging
# sys-fs/cryptsetup and sys-fs/lvm2 was the stated prerequisite. That is no
# longer true, measured inside the published ghcr.io/tuna-os/guppy:gnome:
#
#   /usr/sbin/cryptsetup      present
#   /usr/sbin/dmsetup         present
#   dracut modules 51bootc, 70crypt, 70dm   all installed
#
# so every module the shared config asks for is satisfiable on this base today.
#
# What the gap cost: with no drop-in, dracut never added 51bootc, and `lsinitrd`
# on that same image's initramfs matched ZERO ostree/bootc files. Nothing then
# prepared the deployment at boot, so /sysroot stayed the PHYSICAL root and
# switch-root refused it --
#
#   Failed to switch root: Specified switch root path '/sysroot' does not seem
#   to be an OS tree. os-release file is missing.
#
# -- dropping guppy:xfce to an emergency shell with the disk already unlocked
# and /sysroot already mounted (LUKS run 31232170155). Every other variant was
# immune because they all run this script.
#
# The --omit on the command line stays: it covers this build, while the drop-in
# written near the top of the file is what reaches tacklebox's ISO-time rebuild
# and post-install kernel updates.
