archangel/custom/zfssnapshot, branch mainArch Linux installer ISO — ZFS-on-root or BTRFS, doubles as rescue disk
https://git.cjennings.net/archangel/atom?h=main2026-02-23T17:54:25+00:00refactor: rename custom/ to installer/ for clarity2026-02-23T17:54:25+00:00Craig Jenningsc@cjennings.net2026-02-23T17:54:25+00:00urn:sha1:fd2ea796b20bcbebea19c43978fb08e3cd6754ed
The custom/ directory name was an archiso implementation detail. Renamed
to installer/ which clearly communicates that this directory contains the
installer scripts and utilities that ship on the ISO.
Updated all references in build.sh, Makefile, test-install.sh, and README.
scrub personal info and make distribution targets configurable2026-02-23T12:02:17+00:00Craig Jenningsc@cjennings.net2026-02-23T12:02:17+00:00urn:sha1:2b842fcd47ac24b9da7f192f64b78f83e8fc45af
Remove personal email addresses, hardcoded paths, and infrastructure
references to prepare for open-source release. Distribution targets
in build-release are now configurable via environment variables,
and archsetup inclusion is opt-in.
fix: correct broken shebangs in zfssnapshot and zfsrollback2026-02-23T05:22:48+00:00Craig Jenningsc@cjennings.net2026-02-23T05:22:48+00:00urn:sha1:8ef5c24abd55d3fe7dafe93687be5928e0152c02

Replace GRUB with ZFSBootMenu bootloader2026-01-23T05:21:18+00:00Craig Jenningsc@cjennings.net2026-01-23T05:21:18+00:00urn:sha1:3e70ba84c15d69f48f436239e7f0ac9628464c55
This is a major change that replaces the GRUB bootloader with ZFSBootMenu,
providing native ZFS boot environment support.
Key changes:
- EFI partition reduced from 1GB to 512MB (only holds ZFSBootMenu)
- EFI now mounts at /efi instead of /boot
- Kernel and initramfs live on ZFS root (enables snapshot boot with matching kernel)
- Downloads pre-built ZFSBootMenu EFI binary from get.zfsbootmenu.org
- Creates EFI boot entries for all disks in multi-disk configurations
- Syncs ZFSBootMenu to all EFI partitions for redundancy
- Sets org.zfsbootmenu:commandline on zroot/ROOT for kernel cmdline inheritance
- Sets bootfs pool property for default boot environment
- AMD GPU workarounds (pg_mask, cwsr_enable) added to kernel cmdline when AMD detected
Deleted GRUB snapshot tooling (no longer needed):
- custom/grub-zfs-snap
- custom/40_zfs_snapshots
- custom/zz-grub-zfs-snap.hook
- custom/zfs-snap-prune
Updated helper scripts:
- zfssnapshot: removed grub-zfs-snap call, shows ZFSBootMenu tip
- zfsrollback: removed grub-zfs-snap call, notes auto-detection
Tested configurations:
- Single disk installation
- 2-disk mirror (mirror-0)
- 3-disk RAIDZ1 (raidz1-0)
- All boot correctly with ZFSBootMenu
Add zfssnapshot and zfsrollback scripts to ISO2026-01-19T14:39:28+00:00Craig Jenningsc@cjennings.net2026-01-19T14:39:28+00:00urn:sha1:da3e568d6554458e03cb3d9eee5a820b7e970bab
Copied from archsetup to make these tools available on the live ISO
for rescue scenarios and post-install management.
zfssnapshot:
- Creates recursive snapshots across all pools
- Timestamps with descriptive labels (YYYY-MM-DD_HH-MM-SS_description)
- Integrates with grub-zfs-snap for boot menu updates
zfsrollback:
- Interactive fzf-based snapshot selection
- Two modes: single dataset or all matching datasets
- Safety warnings showing what will be destroyed
- Special genesis rollback warning
