feat: add disk-deploy core, disk image builder, and installer
- deploy-disk.sh: the shared "write a finished system to a disk" step — partition (GPT bios/efi) -> btrfs layout via btrfs/init.sh -> rsync rootfs -> chroot (real fstab, GRUB, hostname). Carries the optional ARCLINE_SIGN hook; the signing tooling itself lands in a later commit. - apply-fstab.sh: renders the edition fstab template with real root/efi UUIDs and drops the swap line. - build-image.sh: rootfs -> bootable qcow2/raw disk image (sparse file + loop device + deploy), the cloud edition's primary output. - install.sh: scripted installer for a real disk, confirmation-gated. - Makefile: image-<edition> targets (+ minimal variants); build-edition.sh learns the "image" stage; cloud metadata now ships a disk image. - check-host-deps.sh / GitLab CI: add gdisk, parted, rsync, dosfstools, qemu-utils, dpkg, sbsigntool to the build image.

# 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).
