# 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.
