stage-usb-share.sh --no-blancco-release leaves out boot-tools/blancco's vendor release (config.img carries this site's licensing Wi-Fi password and location) and the unused blancco-uki.efi. The KB's Part 4 now has the site load its own Blancco 7.20 ISO on Updates > Blancco releases. The Wi-Fi password is gone from SITE-CUSTOMIZATION.md.

# stage-usb-share.sh - Put everything Build-PxeUsb.ps1 needs into a folder
|
|
# on a share, so a Windows PC can build the installer USB from it.
|
|
#
|
|
# Usage:
|
|
# scripts/stage-usb-share.sh [--iso FILE] [--payload-root DIR] [--no-blancco-release] [DEST]
|
|
#
|
|
# DEST defaults to ~/pxe-images/pxe-usb (the [pxe-images] Samba share; on
|
|
# the work PC: \\<this PC>\pxe-images\pxe-usb, usually Z:\pxe-usb). It gets:
|
|
# - the repo as committed (git archive HEAD: uncommitted edits are NOT
|
|
# staged, so the stick matches a commit);
|
|
# - the payload folders (offline-packages, pip-wheels, boot-files,
|
|
# boot-tools, enrollment, bios-staging, drivers-staging, site-content)
|
|
# as hard links, so they cost no extra disk space;
|
|
# - the Ubuntu ISO offline-packages/ was built for (hard link);
|
|
# - STAGED.txt: commit, date, sizes.
|
|
# Then on the work PC: copy the folder to a local disk (C:\pxe-usb) and
|
|
# double-click Build-PxeUsb.cmd (KB: docs/kb/How_To_Deploy_PXE_Server_New_Site.html).
|
|
#
|
|
# --no-blancco-release leaves out the Blancco release (the vendor files from
|
|
# boot-tools/blancco: kernel, initramfs, microcode, rootfs, and config.img
|
|
# with this site's preferences and licence files) and the unused
|
|
# blancco-uki.efi. Use it for a folder going to another site: that site
|
|
# uploads its own Blancco ISO on Updates > Blancco releases.
|
|
#
|
|
# The new copy is built beside the old one and swapped in when complete.
|
|
# Run capture-site-content.sh --apply first so site-content/ is current.
