Actions

Required binaries: zpool, zfs. Actions that call a missing binary fail at run time — install these on the host before relying on the pack.

Install

emisar pack install validates the pack and verifies its content hash before copying it into /etc/emisar/packs. The --hash below pins the install to the exact bytes on this page — a tampered copy is rejected. After install, reload the runner; it re-reads the catalog and advertises every action.

content hash: sha256:530a8cda3da17199f2b8a12e45c757fcc7e0d42f633d460ee6fbb46eaf90abfc

on the runner host

sudo emisar pack install zfs \
  --hash sha256:530a8cda3da17199f2b8a12e45c757fcc7e0d42f633d460ee6fbb46eaf90abfc \
  --dest /etc/emisar/packs

# Reload so the runner re-reads the catalog:
sudo systemctl reload emisar
