Two changes in one:
1. grub-blancco.cfg reverts to booting vmlinuz-ubuntu + kexec-initrd.img
(the switch_root path from commit dd2fec5). b7cd097 had switched
back to Blancco's native vmlinuz-bde-linux via TFTP for "hardware
compat," but that turned out to regress on modern Dell fleet
hardware - Blancco's packaged kernel lacks igc (Intel I225/I226 on
Latitude 5330/5440, Pro-series, newer OptiPlex). Symptom was
successful TFTP fetch of kernel+initrd, then silence at the Blancco
UI ("no network card found") because the rootfs HTTP fetch has no
NIC to use.
The switch_root initramfs built by the Ansible playbook now carries
igc, bnxt_en, r8169, atlantic, and other modern NIC modules, so the
Ubuntu kernel path reliably finds a working NIC across the whole
fleet before HTTP-fetching airootfs.sfs and kexec'ing into Blancco.
Native kernel still runs under Blancco's control after kexec - only
the *loader* kernel changes.
The grubx64.efi binary (embedding this config via grub-mkstandalone)
was rebuilt and pushed to /var/www/html/blancco/ on both PXE servers
(.1 and .2). Old binary kept as grubx64.efi.bak-<timestamp> on each.
2. .gitignore: negate boot-tools/blancco/grub-blancco.cfg so this one
file is version-controlled. boot-tools/ is otherwise local cache
artifacts (kernel/initrd/sfs extracted from Blancco ISO, grubx64.efi
built output). grub-blancco.cfg is source-of-truth and must not be
re-derived; any new PXE server build needs the exact same content
or the Blancco boot chain regresses.
