Closes N100 F1 (HIGH): cheap AMI (AN3PLUS 0.01-class) UEFI firmware can't
relocate the ISO's stock signed GRUB from USB (relocation 0x0). The run's live
grub-mkimage workaround is now a first-class pipeline mode.
- build-felhom-iso.sh: --loader shim|mkimage (default shim, byte-for-byte
unchanged; profile-settable FELHOM_LOADER; --loader wins). Loud banner +
manifest loader:/grub-mkimage: fields + -mkimage filename suffix.
- mkimage-surgery.sh (new): post-prepare-iso, in the assistant container. Builds
a monolithic grub-mkimage loader from the ISO's own GRUB (module set from its
grub.cfg; embedded search --fs-uuid -> configfile the real menu). Swaps it into
the ISO9660 tree (real lowercase path) + the efi.img ESP; xorriso re-master
preserves BIOS-hybrid + UEFI + GPT-ESP, drops only Apple HFS+/APM. Recipe from
the N100 run evidence, not re-derived.
- Dockerfile.assistant: grub-common + grub-efi-amd64-bin + mtools + dosfstools.
profiles/n100.profile (new, mkimage + SB-off note).
- Validated on nested VM 311 (RUNBOOK-B legs): leg1 shim boots+installs under
OVMF SB-enforcing + SeaBIOS; leg2 mkimage boots+installs under SB-off; leg3
(red-proof) mkimage under SB-enforcing FAILS Access Denied (unsigned -> SB must
be OFF); leg4 surgery byte-identical payload. bash -n + shellcheck clean.
Physical N100 closure folds into the rehearsal (n100-safety match-nothing ISO
built + sha-recorded, unbooted). PXE stays a deferred R-21 note.
scripts/iso/: a DooPlex pipeline (build-felhom-iso.sh + Dockerfile.assistant) that
turns the official PVE ISO into a Felhom auto-install ISO whose first-boot stub
installs a retry-forever felhom-bootstrap unit which unattended-fetches
felhom-host-install.sh from the public felhom.eu/scripts channel and runs it until the
host is enrolled + a guest provisioned. host-install is UNMODIFIED (invoked only).
- build gates the answer on validate-answer OUTPUT text, never $? (spike S1 exit-0 trap)
- stub is from-iso, fully-up, exactly-once; retry unit owns all network work (S8a)
- retry-vs-resume encoded once: plain first, --resume when install state exists (v1.11.3)
- secret-bearing (embeds the retrieval passphrase): supervised/single-use; env shredded on success
Validated on VM 310: build gate + red-proof, disk-filter fail-safe, chain + retry,
resume-decision, exactly-once, no-net retry+recovery. Terminal host-install rc-0 success
operator-gated (drill customer needs the password-gated create-UI). scripts v1.16.0;
ROADMAP R-21 -> in-progress. Detail in REPORT.md.
