# bootstrap-all.sh — push agent SSH key + passwordless sudo to remaining systems.
#
# SSH is the ONLY approved access channel (see AGENTS.md "Access-channel
# policy: SSH only"). This script reaches systems that still allow password
# auth over sshd. Systems that reject password auth (publickey-only) cannot
# be reached this way — see the CONSOLE-ONLY section printed at the end.
#
# Two escalation methods:
#   sudo → Ubuntu-style systems (no root pw; localuser has sudo)
#   su   → Debian-style systems (root has a password)
#
# Passes AGENT_USER so agent-bootstrap.sh targets the correct unprivileged
# user. You enter passwords interactively. Idempotent: safe to re-run.
#
# Verified state (access-matrix.sh, 2026-08-10): 68/70 non-excluded systems
# at intended access state. Only tsys-siem remains below.
