Install

emisar pack install fetches this pack, re-validates it, and verifies its content hash against the --hash below — the exact bytes this page was rendered against, so a tampered copy is rejected — before copying it into the runner's packs dir. The command reloads a running daemon itself; no manual restart.

on the runner host 
sudo emisar pack install multipath --hash sha256:11418e0a098f4d67f2b961d17fbaeab15b71110f95865f7a176fdc02e4fc1223
