Boot menu: "Clonezilla: back up this PC" and "restore this PC" ask for the
machine number and boot Clonezilla (64-bit with Debian shim, or 32-bit
i686 by cpuid) with ocs_repository=smb3://clonezilla:<pw>@server/clonezilla/,
ocs_prerun fetching clonezilla-scripts/pxe-cz.sh and ocs_live_run running
it. The script validates the machine number, saves
<machine>-<YYYY-MM-DD-HHMM> (server time), writes pxe-meta.txt, runs
ocs-chkimg, and restores only that machine's images with -k1 -r after a
typed YES. The old entry is "Clonezilla: manual".
Playbook: clonezilla Samba user for the [clonezilla] share only, password
from clonezilla_smb_password (validated, filled into the menu
placeholder), scripts installed to the web root.
Webapp: Clonezilla backups page lists image folders and zips grouped by
machine number with serial/model/version/check, serial mismatch flag,
delete, move to another machine, streamed tar download, disk space bar
and an explicit keep-last-N retention with preview. Tests and a VM test
plan added.
H1 corp_admin_cidrs (UFW 22/9009 on the corp NIC from these only; refuses
when it would lock out the current SSH client) and corp_ssh_password_auth
(sshd drop-in, passwords only from the imaging subnet). Defaults keep the
current behaviour and print a loud warning.
H2 pxe-netplan-apply.sh: pre-flight refusal (pxe-MAC NIC holds the default
route, a DHCP lease or the route to an SSH client), run from the USB
before anything changes; post-apply checks (names, imaging IPv4, corp
IPv4 back within 30 s, SSH route) and a 120 s systemd-run auto-revert.
H3 restore() puts the previous NIC names back (two-phase rename via
temporary names, so swaps work) before generate + apply.
H4 a failed rename is fatal (restore + exit 1); the play drops the old
any-interface UFW rules only after verifying both NICs and their
per-interface SSH rules.
H5 first-boot checks the playbook exit code, retries at next boot (max 5),
writes /var/lib/pxe-firstboot.failed and /etc/issue + /etc/motd banners.
M1 build-usb.sh verifies iPXE files against the playbook pins, every wheel
against its own package's hashes, drops the unpinned pip fallback,
requires --site-vars or --no-site-vars.
M2 webapp restarts when the code, wheels or unit changed.
M3 ignore-carrier on the imaging NIC; ip_nonlocal_bind kept for the
apache/networkd boot race.
M4 menu suffix must match blancco_kver; missing kernel with no earlier
build is fatal; a live menu with the staged Blancco test entry is not
overwritten.
M5 build-proxmox-iso.sh is unsupported (hard exit); use build-usb --image.
M6 deploy-unattend.sh: password via SSHPASS env and sudo stdin only,
%q-quoted remote args, sha256 check of the live file; lint-unattend.py
reads PXE_SERVER/PXE_USER/PXE_PASS and uses sshpass -e.
M7 the playbook lints the unattend files before the force: yes copies
(lint-unattend.py ships on CIDATA as scripts/); pre-commit ACMR.
M8 Blancco initramfs build: no ignore_errors, pipefail, trap cleanup.
Also: Send-ImagingStage.ps1 deploy, carrier hook install tasks
(pxe-nic-carrier, networkd-dispatcher), L1 imaging-active hold
(allow_disruptive) and no iPXE downgrade below an Updates-page install,
L2 iso-volid, L3 kver pin read from the playbook, L4 cp -rL, L5 refuse
>= 4 GiB WinPE files, L6 PIP_DIR wipe guard, L7 per-package wheel hashes,
no online fallback, L8 check-updates.py (apt_pkg/cached compare, all
components, exit 2 on no debs / bad answers).
Every server has an imaging NIC (static, the only one that serves
DHCP/TFTP/HTTP boot/SMB) and a GE corporate NIC (DHCP client, SSH and the
webapp on 9009). The playbook guessed the PXE NIC and the installer put
172.16.9.1/24 on every en* NIC, so a two-NIC box could answer on the GE
network.
- New per-site vars pxe_nic_mac / corp_nic_mac (required, from
playbook/site-vars.yml or -e; template site-vars.example.yml), stable
names pxe_nic_name / corp_nic_name (default pxe0 / corp0, overridable),
pxe_server_ip, pxe_subnet, DHCP range. pxe_imaging_mac / pxe_ge_mac are
derived from them. The play stops before touching anything if a MAC is
unset, malformed, duplicated or not on the box (lists the box's NICs).
- Heuristic NIC detection and the single-NIC netplan task replaced by a
two-NIC netplan template (match macaddress + set-name), installed by
pxe-netplan-apply.sh: validate in a scratch root, back up, generate,
rename, apply, restore the previous config on any failure. cloud-init
network config disabled so it cannot rewrite it.
- dnsmasq: /etc/dnsmasq.d/pxe-nic-only.conf from the vars (interface=,
except-interface=, no-dhcp-interface=); dnsmasq.conf IP/range from vars.
- UFW per interface: imaging NIC 22, 67/udp, 69/udp, 80, 4433, 445, 139,
137/udp, 138/udp, 9009; GE NIC 22 and 9009 only. Old any-interface rules
and the stale 9011 rule removed after the new ones are in.
- sysctl drop-in: IPv4/IPv6 forwarding off; ip_nonlocal_bind so Apache
can bind the imaging IP before the address is up.
- Samba [global]: interfaces = 127.0.0.0/8 <imaging NIC>, bind interfaces
only. Apache 80 and 4433 on the imaging IP only; 9009 stays on all (TODO:
the webapp has no auth).
- autoinstall: DHCP only on en*, no static 172.16.9.1; apt geoip off and
offline-install fallback now that the corp NIC may have a lease.
- Blancco UEFI/Secure Boot: blancco_kver (7.0.0-34-generic) drives the
kernel, initramfs and modules builds instead of the running kernel;
outputs vmlinuz-ubuntu-70, kexec-initrd-70.img, kmod-<kver>.tar.gz as the
menu and blancco-init.sh expect; creates: guards keyed on the full kver.
Ubuntu's shimx64.efi.signed published as blancco/shimx64.efi.
download-packages.sh adds shim-signed, linux-generic-hwe-24.04 and the
pinned linux-image/modules/modules-extra for BLANCCO_KVER.
Rendered with the live MACs and names, netplan generate output is
identical to the live config; pxe-nic-only.conf and the Samba binding
match live directive for directive.
