+# Task: Remove zfssnapshot and zfsrollback from archsetup
+
+## Summary
+Remove the `zfssnapshot` and `zfsrollback` scripts from archsetup's dotfiles. These scripts are now provided by the archzfs ISO and installed to `/usr/local/bin/` during `install-archzfs`.
+
+## Files to Remove
+- `dotfiles/system/.local/bin/zfssnapshot`
+- `dotfiles/system/.local/bin/zfsrollback`
+
+## Reason for Change
+These scripts need to be available immediately after a fresh install from the archzfs ISO, before archsetup runs. Key use cases:
+
+1. **Rescue scenarios**: Rolling back from live USB when the installed system won't boot
+2. **Genesis rollback**: If archsetup fails mid-run, user can rollback to genesis and retry
+3. **Script availability**: The scripts themselves must survive a genesis rollback (they're now part of genesis snapshot)
+
+By including them in the ISO and `install-archzfs`, they're guaranteed to be present from first boot, with fzf also installed as a dependency.
+
+## Changes Made in archzfs
+- Added `custom/zfssnapshot` and `custom/zfsrollback`
+- `build.sh` copies them to `/usr/local/bin/` on the ISO
+- `install-archzfs` installs `fzf` to target system (required by zfsrollback)
+- fzf was already in ISO package list
+
+## Note: Keep fzf in archsetup
+Archsetup should continue to install `fzf` in its package list. Archsetup can run on vanilla Arch installs with ext4 or btrfs (not just ZFS from archzfs ISO), where `install-archzfs` would not have run and fzf wouldn't be present.
