* fix: correct broken shebangs in zfssnapshot and zfsrollbackCraig Jennings2026-02-221-1/+1
| | | | #!/bin/env bash doesn't exist — changed to #!/usr/bin/env bash.
* Replace GRUB with ZFSBootMenu bootloaderCraig Jennings2026-01-221-8/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Fix zfsrollback to process children before parentsCraig Jennings2026-01-191-2/+3
| | | | | | Sort datasets by path depth (deepest first) before rolling back. ZFS requires children to be rolled back before their parents, otherwise rollback can fail or skip datasets.
* Increase fzf height in zfsrollback to 70%Craig Jennings2026-01-191-3/+3
| | | | | 40% was too small on console, showing only ~2 lines. 70% gives roughly 2/3 of screen for snapshot selection.
* Add zfssnapshot and zfsrollback scripts to ISOCraig Jennings2026-01-191-0/+184
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
