The edition package lists installed BOTH grub-pc and grub-efi-amd64 (+ shim-signed). Those provide the same bootloader role and conflict in apt, so every rootfs build failed with "unable to correct problems, you have held broken packages". A rootfs now carries exactly ONE bootloader, chosen by the BOOT variable (mirroring the existing --boot bios|efi deploy option): - versions.mk / common.sh: BOOT := bios (bios -> grub-pc, efi -> grub-efi-amd64 + shim-signed + mokutil), exported via the Makefile. - build-rootfs.sh validates BOOT early and injects the matching boot packages into the apt install; the static package lists no longer contain any grub package. - deploy-disk.sh / build-image.sh / install.sh default --boot from the same BOOT variable, so a rootfs and the artifact deployed from it can never disagree (BOOT=efi make image-cloud produces a UEFI image). - mokutil is now installed explicitly in the efi flavour (it was not pulled in because we install with --no-install-recommends). - docs updated (building.md knob + rationale, secureboot.md note).

# Arcline OS — deploy a rootfs to a disk
|
|
#
|
|
# scripts/deploy-disk.sh <device> <rootfs> <edition> [--boot bios|efi]
|
|
#
|
|
# The shared "write a finished Arcline system to a block device" step, used by
|
|
# both the disk image builder (scripts/build-image.sh) and the scripted
|
|
# installer (scripts/install.sh):
|
|
#
|
|
# 1. partition the device (GPT):
|
|
# bios: [1M BIOS boot] + [btrfs root]
|
|
# efi: [512M EFI] + [btrfs root]
|
|
# 2. mkfs.btrfs + btrfs/init.sh → @, @home, @log, @snapshots
|
|
# 3. rsync the rootfs into @
|
|
# 4. chroot: write real /etc/fstab (real UUIDs), install GRUB, update-grub
|
|
#
|
|
# DANGER: this wipes <device>. There is no confirmation — the callers are
|
|
# responsible for safety (build-image.sh always uses a throwaway loop device;
|
|
# install.sh asks for explicit confirmation).
