The script that sets the SSH, PAM, pwquality and auditd baseline on twelve
containers existed only as a root-owned copy on the machines it hardens.
Bring it into the repo so a change reaches one place instead of twelve.
Two substantive changes over the copy that shipped on 2026-07-24:
- Deny forwarding per option instead of via DisableForwarding. Same effect,
but DisableForwarding overrides every other forwarding option and is
invisible in sshd -T, which makes a rejected port-forward read as a
configuration that should work.
- Quote the command substitution in MODDIR (SC2046).
The header and README now record the rollout command, the containers left
unhardened as break-glass foundation, and why host-specific exceptions must
live in a drop-in that sorts after 99-cis-hardening.conf.
