Booting via BMC virtual CD reads the ~2.8 GB filesystem squashfs
sequentially during the live-boot toram copy; a mid-read drop of the
redirected medium loses the whole copy and fails the boot (v14). Split
the rootfs into self-contained semantic layers so a retry re-reads at
most one ~500-700 MiB layer, not everything. This is a resilience /
reduced-re-read mechanism, not a fix for the virtual-media instability.
NVIDIA variants now ship 7 layers (00-base, 05-firmware, 08-desktop,
10-nvidia-driver, 20-nvidia-platform, 30-nvidia-cuda-libs,
40-nvidia-dcgm-cuda) plus an explicit live/filesystem.module that fixes
their OverlayFS order; amd/nogpu keep a single squashfs.
- lib/squashfs-layers.sh: deterministic classifier (dpkg file ownership
plus explicit rules for build.sh-injected files, never a path
substring), per-layer mksquashfs, 800 MiB hard ceiling, unsquashfs -s
plus strict extraction of every layer, merged-rootfs bootability check.
- build.sh: split the monolith after the full lb build, verify and merge,
write the module file, delete the monolith only then; abort before ISO
assembly on any failure. Runs the builder test suites up front.
- fast-path: force a full build for a multi-layer medium;
fast_path_repack_squashfs hard-refuses (it would drop layers).
- iso-validation.sh: validate_iso_squashfs_layers (module vs layer set
match, size ceiling, no lone giant squashfs) and
validate_iso_media_integrity (xorriso -check_media).
- bee-install: honour filesystem.module order, abort on any layer failure.
- 9013-toram-retry: record the real rsync exit code (it printed a false
rc=0) and correct the "resumes the tail" comment (rsync without
--partial keeps only fully-copied layers). No unsafe partial resume.
- tests: test-squashfs-layers.sh plus a multi-layer guard in
test-build-libs.sh; both run at the top of every build.
- docs: bible-local architecture and decision, iso/README, iso-build-rules.
Verified by a full nvidia build: 7 layers 622/199/256/466/37/567/562 MiB,
every validator passes, xorriso -check_media good, merged rootfs bootable.

- grub.cfg: add "load to RAM (toram)" entry to advanced submenu
- install_to_ram.go: resume from existing /dev/shm/bee-live copy if
source medium is unavailable after bee-web restart
- tasks.go: fix "Recovered after bee-web restart" shown on every run
(check j.lines before first append, not after)
- bee-install: retry unsquashfs up to 5x with wait-for-remount on
source loss; clear error message with bee-remount-medium hint
- bee-remount-medium: new script to find and remount live ISO source
after USB/CD reconnect; supports --wait polling mode
- 9000-bee-setup: chmod +x for bee-install and bee-remount-medium

Copies the live system to a local disk via unsquashfs — no debootstrap,
no network required. Supports UEFI (GPT+EFI) and BIOS (MBR) layouts.
ISO:
- Add squashfs-tools, parted, grub-pc, grub-efi-amd64 to package list
- New overlay script bee-install: partitions, formats, unsquashfs,
writes fstab, runs grub-install+update-grub in chroot
Go TUI:
- Settings → Tools submenu (Install to disk, Check tools)
- Disk picker screen: lists non-USB, non-boot disks via lsblk
- Confirm screen warns about data loss
- Runs with live progress tail of /tmp/bee-install.log
- platform/install.go: ListInstallDisks, InstallToDisk, findLiveBootDevice
