blancco: quiet PXE boot, full trace with blancco.debug=1
The UEFI loader ran under set -x and printed modprobe -v, ip link and ip addr, and neither kernel cmdline had quiet, so the screen scrolled hundreds of lines before the Blancco GUI. Now: - quiet loglevel=3 on both Blancco kernel lines (also quiets systemd) - init clears the screen and prints one line per step - blancco.debug=1 on the cmdline restores the old trace - failure paths still print their diagnostics and drop to a shell Live GetPxeScript.aspx changed to match (backup .bak-20261005-pre-quiet) and kexec-initrd.img rebuilt.
