TODO — diskless fleet boot system

Persistent backlog, kept in sync with the working session task tracker. Status: [ ] pending · [~] in progress · [x] done.

---

[ ] 1. Port the dracut module off network-legacy → network-manager

Durable replacement for the current dhcp-client stopgap. dhclient is deprecated in RHEL 9 and will eventually leave the repos; the build only works today because the provisioner installs dhcp-client so network-legacy passes dracut's check().

• Rewrite both network bring-up paths in ../files/dracut/95dot1x-macsec/dot1x-macsec-up.sh: the secure path's ifup macsec0 and the rd.dot1x=0 bypass path's ifup $NIC — use nmcli/NetworkManager-in-initramfs (or ip= cmdline + the nm module) instead.
• Change depends() network-legacy → network-manager in ../files/dracut/95dot1x-macsec/module-setup.sh.
• Update add_dracutmodules in ../files/etc/dracut.conf.d/90-diskless.conf.
• Drop dhcp-client from the provisioner dnf install in ../diskless.pkr.hcl.
• Re-verify the lsinitrd assertion.
• Gate: full boot-chain smoke test (swtpm + hostapd + FreeRADIUS) before merge, per CLAUDE.md.

[ ] 2. Apply RHEL9 STIG hardening to the built image

OpenSCAP + SCAP Security Guide (xccdf_org.ssgproject.content_profile_stig), run as a Packer provisioner after dnf install and before the dracut/initramfs build and cleanup.

• Tailoring (autotailor): unselect rules this architecture can't satisfy — separate-partition rules (single erofs root + tmpfs overlay; satisfy intent with nodev,nosuid,noexec tmpfs mounts), GRUB/kernel-cmdline rules (no GRUB), and AIDE/file-integrity rules (dm-verity is the documented compensating control).
• Kernel params → UKI cmdline in ../scripts/extract-artifacts.sh before signing: audit=1 audit_backlog_limit=8192 slub_debug=P page_poison=1 vsyscall=none (+ fips=1 if FIPS).
• Reproducibility guard: strip non-deterministic remediation output (SSH host keys → regen at boot into overlay, AIDE db, timestamps, fresh UUIDs) so the verity hash stays stable.
• Audit logging: audisp-remote/rsyslog to a central collector addressed by DNS name (host-generic).
• Optional FIPS: fips=1 cmdline + 01fips dracut module + FIPS crypto policy.
• CI: run oscap eval (no --remediate) to publish an ARF+HTML STIG report as a build artifact; optionally hard-fail below a score threshold.
• Decisions needed before implementing: FIPS on/off · remote-audit collector DNS name (or ephemeral/none for lab) · CI fail-on-score threshold vs report-only.
• Note: orthogonal to the rd.dot1x=0 test toggle, but a full STIG production posture wants 802.1X re-enabled.

[ ] 3. Roll the errata into design doc v3

Once the boot path is validated and item 1 lands, fold design-v2-errata.md into the source design document and re-export a v3 PDF (key change: rootovl → systemd.volatile=overlay in §3 step 8 and §5). Retire/reset the errata afterward. Needs the design-doc source (not in this repo).
