The build_grub2_204.sh script was patching Ventoy's modsrc from 65536 to 131072 sectors (bumping expected ESP size from 32MB to 64MB). After reducing our ESP size to 32MB to match Ventoy exactly, this patch now needs to be reversed (131072 -> 65536) so the GRUB2 layout check accepts our 32MB ESP. Built GRUB2 EFI binary with corrected checks. Reinstalled payload.

# build_grub2_204.sh — Build GRUB2 2.04 with Ventoy modifications for hiperiso.
|
|
# ---------------------------------------------------------------------------
|
|
# hiperiso uses Ventoy as the GRUB substrate. This script unpacks the
|
|
# upstream GRUB2.04 source, overlays Ventoy's `grub2-modsrc` patch set,
|
|
# and builds the stock Ventoy GRUB binary. The rebranding layer (hiperiso
|
|
# kernel cmdline, JSON config, initramfs bridge) lives in
|
|
# `host/initramfs/` and the installed payload's `grub.cfg`, NOT in GRUB.
|
|
#
|
|
# The hiperiso source tree in `src/grub2/` is retained for reference but
|
|
# intentionally NOT compiled in here — it's an unfinished rebrand attempt
|
|
# that's blocked on partial modsrc/sed mismatches. The substrate approach
|
|
# is the supported path; the historical rebrand sources are kept only
|
|
# for context. See INTERFACES.sh (Build Architecture section) for the
|
|
# full rationale.
|
|
#
|
|
# Usage: scripts/build_grub2_204.sh
|
|
# Output: grub2/bin/BOOTX64.EFI, grub2/bin/grubx64_real.efi, grub2/bin/grubx64.efi
