Every cluster this bastion builds was pinned to ipam=kubernetes, which makes it
permanently single-stack: Cilium reads node.spec.podCIDRs, the controller-manager
writes that once at node join and never revises it, so adding IPv6 later fails
with `required IPv6 PodCIDR not available` and needs a rebuild.
cluster-pool puts allocation in the CiliumNode CRD, where the operator can add
an address family to a running node. Proven in labsim (842408c). It is also
Cilium's own default -- ipam=kubernetes was the deviation.
Pool matches the k3s cluster-cidr (10.42.0.0/16, /24 per node), so a node gets
the same CIDR shape it would have had. IPv4-only for now: the IPv6 pool wants an
apiserver carrying an IPv6 service CIDR, which is a separate change.
Mirrors @michal/cilium-values ciliumBaseValues (cilium-values@11ee509), which
these paths track but do not import.

Kickstart installs on real hardware failed silently — no error reporting,
only 3 progress callbacks, zero log streaming. This overhaul makes every
install fully observable.
Kickstart improvements:
- Error trapping in %pre and %post (trap ERR sends failure details to bastion)
- 12+ granular progress stages (was 3): SSH, hostname, k3s prep, EFI boot, metadata
- Background log streamer: tails %post output and batch-sends to /api/log
- bastion_log() function for explicit log lines from kickstart scripts
Bastion API:
- POST /api/log — receives raw log lines from kickstart (single or batch)
- InstallLogBuffer — per-MAC ring buffer (2000 lines) + file persistence
- GET /api/logs/:mac — now returns log_lines + log_total alongside stages
- SSE /api/logs/:mac/follow — uses named events (event: stage vs event: log)
- Progress events forwarded to labd via bastion-progress WebSocket message
- Post-provision k3s logs routed through progressBus (was console-only)
dnsmasq fixes found during VM testing:
- HTTP Boot filename: ipxe-real.efi → ipxe.efi (leftover from old 2-stage approach)
- pxe-service directives: only in proxy mode (breaks OVMF PXE in full mode)
- PXEClient vendor class echo for UEFI firmware compatibility
Integration tests:
- PXE boot test: blank UEFI VM → dnsmasq → HTTP Boot → iPXE → bastion → install
- ISO boot test: blank VM boots from bastion-generated ISO → same flow
- Shared helpers: pxe-network (no DHCP, nftables fix), pxe-vm (UEFI + ISO boot)
- test-provision.sh: runs both PXE + ISO tests with prerequisite checks
- 250GB sparse QCOW2 disk (LVM layout needs ~204GB)
201 unit tests passing (11 new).
