sanboot makes the ISO visible to UEFI but invisible to the Linux kernel
after ExitBootServices(). Switch to direct kernel/initrd boot with a small
CPIO overlay containing /pxe-init — a shell script that loads NIC drivers,
configures DHCP, downloads the ISO via wget, and creates a loop device
before handing off to the Proxmox installer init.

The auto-installer menuentry was wrapped in 'if [ -f auto-installer-mode.toml ]'
which never evaluated true. Replace the condition with 'if true' to activate the
built-in auto-installer entry, and only add the answer-url to kernel lines that
already have proxmox-start-auto-installer (rather than modifying the graphical
install entry).

os.ReadFile on the ISO was OOM-killing the container. Switch to 8MB
chunked reads with overlap to handle matches spanning chunk boundaries.

The modified config was 75 bytes larger than the original (5798 vs 5723),
causing the in-place write to be rejected. Strip comment lines and trailing
whitespace to reclaim space for the added auto-installer kernel parameters.

Two fixes: (1) Search entire ISO for grub.cfg content instead of only at
2048-byte sector boundaries — catches the copy inside the EFI boot
partition image that UEFI firmware actually reads. (2) Match kernel lines
by GRUB 'linux' command prefix instead of requiring '/boot/linux' path.
Added detailed logging of original and modified grub.cfg content.

Modifies uploaded ISO's GRUB config in-place to set timeout=0 and inject
proxmox-start-auto-installer + answer-url kernel params, enabling fully
hands-off installation. Adds /api/boot/auto-answer endpoint that identifies
hosts by ARP-resolving the requester's IP to MAC address.

The CPIO-embedded initrd approach failed (too large for iPXE memory).
Instead, use iPXE's sanhook to connect the ISO as a SAN block device
before booting with kernel/initrd. The installer finds the ISO on the
SAN device while we retain control over kernel parameters.

Instead of sanboot (which can't pass kernel params for automation),
switch back to kernel/initrd boot. The ISO is embedded in the initrd
as a CPIO append. A pxe-init wrapper script loop-mounts the ISO
before handing off to the original init, so the installer finds it
as a block device. Uses rdinit=/pxe-init kernel parameter.

The Proxmox installer needs the full ISO to access packages and
installer data. Previously the ISO was deleted after extracting
kernel+initrd. Now we keep it as original.iso and serve it via HTTP.
The iPXE script passes proxmox-iso-url=<url> so the installer
fetches the ISO over the network instead of scanning block devices.

ISO uploads now show a progress bar during file transfer (via XHR
upload.onprogress) and real-time extraction status (via SSE events
through the existing Hub). Falls back to plain form POST if JS is
disabled.

Upload Proxmox ISOs via API or dashboard UI, extract kernel+initrd
using pure-Go iso9660 library, store on disk, and serve over HTTP
for PXE booting. Dynamic kernel/initrd filenames per image replace
the previous hardcoded paths.
